This book was released on 1993 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper the following items will be treated: The present status of dense nuclear matter calculations and constraints on the behavior of the associated equation of state at high densities from data on rapidly rotating pulsars. Recent finding of the likely existence of a mixed phase of baryons and quarks forming a coulomb lattice in the dense cores of neutron stars. Review of important findings of recently performed calculations of rapidly rotating compact stars. These are constructed in the framework of general relativity theory for a representative collection of realistic nuclear equations of state. Establish the minimum-possible rotational periods of gravitationally bound neutron stars and self-bound strange stars. Its knowledge is of fundamental importance for the decision between pulsars that can be understood as rotating neutron stars and those that cannot (signature of hypothetical self-bound matter of which strange stars are the likely stellar candidates. Investigate the properties of sequences of strange stars. Specifically, we answer the question whether such objects can give rise to the observed phenomena of pulsar glitches, which is at the present time the only astrophysical test of the strange-quark-matter hypothesis.

Available in PDF, EPUB and Kindle. Book excerpt: This article consists of three parts. In part one we review the present status of dense nuclear matter calculations, and introduce a representative collection of realistic nuclear equations of state which are derived for different assumptions about the physical behavior of dense matter (baryon population, pion condensation, .possible transition of baryon matter to quark matter). In part two we review recently performed non-rotating and rotating compact star calculations performed for these equations of state. The minimum stable rotational periods of compact stars, whose knowledge is of decisive importance for the interpretation of rapidly rotating pulsars, axe determined. For this purpose two different limits on stable rotation are studied: rotation at the general relativistic Kepler period (below which mass shedding at the star's equator sets in), and, secondly, rotation at the gravitational radiation-reaction instability (at which emission of gravitational waves set in which slows the star down). Part three of this article deals with the properties of hypothetical strange stars. Specifically we investigate the amount of nuclear solid crust that can be carried by a rotating strange star, and answer the question whether such objects can give rise to the observed phenomena of pulsar glitches, which is at the present time the only astrophysical test of the strange-quark-matter hypothesis.

Book Synopsis Rotating Relativistic Stars by : John L. Friedman
Download or read book Rotating Relativistic Stars written by John L. Friedman and published by Cambridge University Press. This book was released on 2013-02-11 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The masses of neutron stars are limited by an instability to gravitational collapse and an instability driven by gravitational waves limits their spin. Their oscillations are relevant to x-ray observations of accreting binaries and to gravitational wave observations of neutron stars formed during the coalescence of double neutron-star systems. This volume includes more than forty years of research to provide graduate students and researchers in astrophysics, gravitational physics and astronomy with the first self-contained treatment of the structure, stability and oscillations of rotating neutron stars. This monograph treats the equations of stellar equilibrium; key approximations, including slow rotation and perturbations of spherical and rotating stars; stability theory and its applications, from convective stability to the r-mode instability; and numerical methods for computing equilibrium configurations and the nonlinear evolution of their oscillations. The presentation of fundamental equations, results and applications is accessible to readers who do not need the detailed derivations.
Book Synopsis Timing Neutron Stars: Pulsations, Oscillations and Explosions by : Tomaso M. Belloni
Download or read book Timing Neutron Stars: Pulsations, Oscillations and Explosions written by Tomaso M. Belloni and published by Springer Nature. This book was released on 2020-10-23 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron stars, whether isolated or in a binary system, display a varied and complex phenomenology, often accompanied by extreme variability of many time scales, which takes the form of pulsations due to the object rotation, quasi-periodicities associated to accretion of matter, and explosions due to matter accreted on the surface or to starquakes of highly magnetized objects. This book gives an overview of the current observational and theoretical standpoint in the research on the physics under the extreme conditions that neutron stars naturally provide. The six chapters explore three physical regions of a neutron star: the space around it, where accretion and pulsar companions allow testing of general relativity its surface, where millisecond pulsation and X-ray burts provide clues about general relativistic effects and the equation of state of neutron matter its interior, of course, inaccessible to direct observations, can nevertheless, be probed with all observational parameters related to neutron star variability.
Book Synopsis Hot and Dense Nuclear Matter by : Walter Greiner
Download or read book Hot and Dense Nuclear Matter written by Walter Greiner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 874 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ladies and Gentlemen, dear colleagues, Welcome in Bodrum to the NASion Hot and Dense Nuclear Matter! Welcome also to Mrs. Governor Dr. Lale AYTAMAN. We are very honored, that you, Governor of the Mugla-State, came here to greet us. We are particularly grateful to you that you offered help and assured us to do everything that we can enjoy two safe weeks in Bodrum, in this wonderful area of your country. I have chosen Bodrum as the place for our NASI because I like this historic region where many cultures meet (e. g. , Oriental and European (Greek, Roman) culture) and where you find numerous places which played a role in ancient science and in early Christianity- I mention Milet (Thales) and Ephesus (Apostle Paulus), both of which are close by. Our NASI will exhibit the most recent developments in high energy heavy ion physics. The meeting is both a school and a conference: A school, because there are very many advanced students, who frequently are themselves already top researchers, attending the lectures of distinguished scientists and leading researchers. It is also a conference because new material, new results of this exciting and wonderful field - our field - high energy heavy ion physics will be presented. It is the topic of hot and dense nuclear matter, which we are focusing on.
Book Synopsis Essential Radio Astronomy by : James J. Condon
Download or read book Essential Radio Astronomy written by James J. Condon and published by Princeton University Press. This book was released on 2016-04-05 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ideal text for a one-semester course in radio astronomy Essential Radio Astronomy is the only textbook on the subject specifically designed for a one-semester introductory course for advanced undergraduates or graduate students in astronomy and astrophysics. It starts from first principles in order to fill gaps in students' backgrounds, make teaching easier for professors who are not expert radio astronomers, and provide a useful reference to the essential equations used by practitioners. This unique textbook reflects the fact that students of multiwavelength astronomy typically can afford to spend only one semester studying the observational techniques particular to each wavelength band. Essential Radio Astronomy presents only the most crucial concepts—succinctly and accessibly. It covers the general principles behind radio telescopes, receivers, and digital backends without getting bogged down in engineering details. Emphasizing the physical processes in radio sources, the book's approach is shaped by the view that radio astrophysics owes more to thermodynamics than electromagnetism. Proven in the classroom and generously illustrated throughout, Essential Radio Astronomy is an invaluable resource for students and researchers alike. The only textbook specifically designed for a one-semester course in radio astronomy Starts from first principles Makes teaching easier for astronomy professors who are not expert radio astronomers Emphasizes the physical processes in radio sources Covers the principles behind radio telescopes and receivers Provides the essential equations and fundamental constants used by practitioners Supplementary website includes lecture notes, problem sets, exams, and links to interactive demonstrations An online illustration package is available to professors
Book Synopsis Neutron Stars, Fast Pulsars, Supernovae and the Equation of State of Dense Matter by :
Download or read book Neutron Stars, Fast Pulsars, Supernovae and the Equation of State of Dense Matter written by and published by . This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We discuss the prospects for obtaining constraints on the equation of state from astrophysical sources. Neutron star masses although few are known at present, provide a very direct constraint in as much as the connection to the equation of state involves only the assumption that Einstein's general theory of relativity is correct at the macroscopic scale. If the millisecond pulses briefly observed in the remnant of SN1987A can be attributed to uniform rotation of a pulsar, then a very severe constraint is placed on the equation of state. The theory again is very secure. The precise nature of the constraint is not yet understood, but it appears that the equation of state must be neither too soft nor stiff, and it may be that there is information not only on the stiffness of the equation of state but on its shape. Supernovae simulations involve such a plethora of physical processes including those involved in the evolution of the precollapse configuration, not all of them known or understood, that they provide no constraint at the present time. Not even the broad category of mechanism for the explosion is agreed upon (prompt shock, delayed shock, or nuclear explosion). In connection with very fast pulsars, we include some speculations on pure quark matter stars, and on possible scenarios for understanding the disappearance of the fast pulsar in SN1987A. 47 refs., 16 figs., 1 tab.

Book Synopsis The Physics and Astrophysics of Neutron Stars by : Luciano Rezzolla
Download or read book The Physics and Astrophysics of Neutron Stars written by Luciano Rezzolla and published by Springer. This book was released on 2019-01-09 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the recent progress in the physics and astrophysics of neutron stars and, most importantly, it identifies and develops effective strategies to explore, both theoretically and observationally, the many remaining open questions in the field. Because of its significance in the solution of many fundamental questions in nuclear physics, astrophysics and gravitational physics, the study of neutron stars has seen enormous progress over the last years and has been very successful in improving our understanding in these fascinating compact objects. The book addresses a wide spectrum of readers, from students to senior researchers. Thirteen chapters written by internationally renowned experts offer a thorough overview of the various facets of this interdisciplinary science, from neutron star formation in supernovae, pulsars, equations of state super dense matter, gravitational wave emission, to alternative theories of gravity. The book was initiated by the European Cooperation in Science and Technology (COST) Action MP1304 “Exploring fundamental physics with compact stars” (NewCompStar).
Book Synopsis Rotating Neutron Stars and the Equation of State of Dense Matter by :
Download or read book Rotating Neutron Stars and the Equation of State of Dense Matter written by and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate the properties of non-rotating as well as rotating neutron stars in the framework of Einstein's theory of general relativity. The nuclear equation of state of neutron star matter (electrically charge neutral many-baryon/lepton system) is calculated for the relativistic Hartree- and Hartree-Fock approximations. The influence of two-particle correlations on the equation of state is taken into account, too. An important result is that the limiting rotational frequency of a neutron star is set by instability modes caused by gravitational radiation reaction, which set in well below the Kerplerian frequency. 20 refs., 7 figs., 3 tabs.

Book Synopsis Studying Compact Star Equation of States with General Relativistic Initial Data Approach by : Enping Zhou
Download or read book Studying Compact Star Equation of States with General Relativistic Initial Data Approach written by Enping Zhou and published by Springer Nature. This book was released on 2020-04-03 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the equation of state (EoS) of compact stars, particularly the intriguing possibility of the “quark star model.” The EoS of compact stars is the subject of ongoing debates among astrophysicists and particle physicists, due to the non-perturbative property of strong interaction at low energy scales. The book investigates the tidal deformability and maximum mass of rotating quark stars and triaxially rotating quark stars, and compares them with those of neutron stars to reveal significant differences. Lastly, by combining the latest observations of GW170817, the book suggests potential ways to distinguish between the neutron star and quark star models.
Book Synopsis Nuclear and Particle Astrophysics by :
Download or read book Nuclear and Particle Astrophysics written by and published by . This book was released on 1990 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: We discuss the physics of matter that is relevant to the structure of compact stars. This includes nuclear, neutron star matter and quark matter and phase transitions between them. Many aspects of neutron star structure and its dependance on a number of physical assumptions about nuclear matter properties and hyperon couplings are investigated. We also discuss the prospects for obtaining constraints on the equation of state from astrophysical sources. Neuron star masses although few are known at present, provide a very direct constraint in as much as the connection to the equation of state involves only the assumption that Einstein's general of theory of relativity is correct at the macroscopic scale. Supernovae simulations involve such a plethora of physical processes including those involved in the evolution of the precollapse configuration, not all of them known or understood, that they provide no constraint at the present time. Indeed the prompt explosion, from which a constraint had been thought to follow, is now believed not to be mechanism by which most, if any stars, explode. In any case the nuclear equation of state is but one of a multitude on uncertain factors, and possibly one of the least important. The rapid rotation of pulsars is also discussed. It is shown that for periods below a certain limit it becomes increasingly difficult to reconcile them with neutron stars. Strange stars are possible if strange matter is the absolute ground state. We discuss such stars and their compatibility with observation. 112 refs., 37 figs., 6 tabs.
Book Synopsis The Cooling of Neutron Stars by : Ronny Kjelsberg
Download or read book The Cooling of Neutron Stars written by Ronny Kjelsberg and published by Lulu.com. This book was released on 2012-06-21 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron stars are the densest objects known in our universe that have not collapsed in on themselves to form a singularity (a black hole). Like black holes they are formed when stars run out of nuclear fuel and radiation pressure can no longer withstand the pull of gravitational forces. This book gives you an in-depth look at how the Direct Urca process is a central element in the cooling of neutron stars after their forming, however it also provides brief introductions to neutron star physics in general, the history of neutron star physics, and pulsars - the pulsating stars that form the observational basis for neutron stars. The book also introduces the different relevant models for an equations of state for neutron stars and a chapter on hyperon matter, before it finally goes on to describe the cooling processes of neutron stars, all with the necessary mathemathical framework for an in-depth analysis.
