Book Synopsis An Introduction to Planetary Nebulae by : Jason J. Nishiyama
Download or read book An Introduction to Planetary Nebulae written by Jason J. Nishiyama and published by Morgan & Claypool Publishers. This book was released on 2018-05-25 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book we will look at what planetary nebulae are, where they come from and where they go. We will discuss what mechanisms cause these beautiful markers of stellar demise as well as what causes them to form their variety of shapes. How we measure various aspects of planetary nebulae such as what they are made of will also be explored. Though we will give some aspects of planetary nebulae mathematical treatment, the main points should be accessible to people with only a limited background in mathematics. A short glossary of some of the more arcane astronomical terms is at the end of the book to help in understanding. Included at the end of each chapter is an extensive bibliography to the peer reviewed research on these objects and I would encourage the reader interested in an even deeper understanding to read these articles.

Available in PDF, EPUB and Kindle. Book excerpt: At the end of a star's life, it wraps itself in a cocoon by spilling out gas and dust. Sometime later, a butterfly-like nebula emerges from the cocoon and develops into a planetary nebula. They are among the most beautiful of the celestial objects imaged by the Hubble Space Telescope. Their structures, like bubbles floating in the void, are complemented by a kaleidoscope of colour emitted by glowing gases. Delicate, lacelike, streamers of gas add to their complexity. The production of a planetary nebula by a star is a milestone in the life of a star, an event that foretells the doom of the star when its central energy source runs out. In this book, Sun Kwok tells the story of the discovery process of the creation of planetary nebulae and of the future of the Sun. Full colour illustrations are included throughout the book.

Book Synopsis The Physics and Dynamics of Planetary Nebulae by : Grigor A. Gurzadyan
Download or read book The Physics and Dynamics of Planetary Nebulae written by Grigor A. Gurzadyan and published by Springer Science & Business Media. This book was released on 1997-04-17 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planetary nebulae are the classic subject of astrophysics. The physical pro cesses occurring in this highly ionized gaseous medium, the formation of emis sion lines in clearly specified conditions, the continuous emission extending from the far ultraviolet up to infrared and radio frequencies, the generation of exotic forms of radiation predicted by atomic physics, along with methods for deciphering the observed spectra and detecting physical and kinematic parameters of the radiating medium, etc. - all these problems form the solid foundations of the physical theory of gaseous nebulae. They are an essential part of the arsenal of powerful tools and concepts without which one cannot imagine understanding and interpreting the enormous diversity of processes taking place in the Universe - in gaseous envelopes surrounding the stars of various classes, from cool dwarfs and flare stars up to hot supergiants, as well as in stellar chromospheres and coronae, in atmospheres of unstable and anomalous stars, in circumstellar clouds and gaseous shells born in nova and supernova explosions, in diffuse nebulae and the interstellar medium, in interacting binary systems, in galaxies with emission lines, in quasars, etc. The last thirty years have seen a turning-point in our knowledge concern ing the very nature of planetary nebulae (PNs). The radio emission of PNs was discovered after it was predicted theoretically. On the other hand, the powerful infrared emission discovered both in the continuum and in emission lines was never expected.

Book Synopsis The Origin and Evolution of Planetary Nebulae by : Sun Kwok
Download or read book The Origin and Evolution of Planetary Nebulae written by Sun Kwok and published by Cambridge University Press. This book was released on 2000-05-25 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative volume provides a comprehensive review of the origin and evolution of planetary nebulae. It covers all the stages of their evolution, carefully synthesizes observations from across the spectrum, and clearly explains all the key physical processes at work. Particular emphasis is placed on observations from space, using the Hubble Space Telescope, the Infrared Space Observatory, and the ROSAT satellite. This book presents a thoroughly modern understanding of planetary nebulae, integrating developments in stellar physics with the dynamics of nebular evolution. It also describes exciting possibilities such as the use of planetary nebulae in determining the cosmic distance scale, the distribution of dark matter and the chemical evolution of galaxies. This book provides graduate students with an accessible introduction to planetary nebulae, and researchers with an authoritative reference. It can also be used as an advanced text on the physics of the interstellar medium.
Book Synopsis Planetary Nebulae by : Harm J. Habing
Download or read book Planetary Nebulae written by Harm J. Habing and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planetary nebulae present a fascinating range of shapes and morphologies. They are ideal laboratories for the study of different astrophysical processes: atomic physics, radiative transfer, stellar winds, shocks, wind-wind interaction, and the interaction between stellar winds and the interstellar medium. In addition, planetary nebulae provide information about the late stages of stellar evolution. In the last five years studies of planetary nebulae have progressed very rapidly and new phenomena and insights have been gained. This is partly due to new observations (e.g. from the Hubble Space Telescope, the ISO satellite and new infrared and millimeter spectrographs) and partly to the advancement of hydrodynamic simulations of the structures of planetary nebulae (PN). Many of these new results were reported at IAU Symposium 180 in Groningen, the Netherlands, on August 26 to 30, 1996. This symposium was dedicated to one of the pioneers of PN research: Stuart Pottasch. These proceedings contain chapters on: Introduction to PN with the basic parameters Distances of PN The central stars of PN The envelopes of PN The evolution from AGB to PN The evolution from PN to white dwarfs PN in the galactic context PN in extragalactic systems The future of PN research . The book contains 29 reviews and more than 200 shorter contributions.
Book Synopsis Planetary Nebulae by : Silvia Torres-Peimbert
Download or read book Planetary Nebulae written by Silvia Torres-Peimbert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every 5 years since 1967 a meeting has been held to discuss the subject of planetary nebulae and their central stars. Previous meetings have been held in Tatranska Lomnica (Czechoslovakia); Liege (Belgium); Ithaca, New York (U. S. A); and London (Great Britain). IAU Symposium 131 was sponsored by IAU Commision 34, on Interstellar Matter and co-sponsored by IAU Commisions 35 and 36 on Stellar Constitution and Theory of Stellar Atmospheres. The symposium was held at the Universidad Nacional Autonoma de Mexico in Mexico City, October 5-9, 1987. It took place in one of the old buildings of the University of Mexico in the downtown area. The inner patio of the building provided very pleasant surroundings for the poster sessions and for extensive discussions among the participants. The meeting was attended by 160 scientists from 22 countries. The Scientific Organizing Committee,under the chairmanship of J.B. Kaler, prepared a comprehensive scientific program based on a set of invited presentations. All contributed papers were presented in poster form. The Scientific Organizing Committee would like to thank the staff of the University of Illinois Department of Astronomy: Dr. Ron Allen for granting financial support; Carol Stickrod, Louise Browning, Deana Griffin and Sandie Osterbur for their help with the organization. IAU provided economic assistance to a group of young astronomers.
Book Synopsis Planetary Nebulae by : R. Weinberger
Download or read book Planetary Nebulae written by R. Weinberger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planetary nebulae are a keystone for the understanding of the evolution of stars, for deep insights into the physical processes prevailing in highly excited dilute nebulae, and for the chemical evolution in galaxies. These objects, displaying an intriguing morphology, have a `short' lifetime of a few tens of thousands of years, and have become one of the best studied classes of celestial sources. However, despite large and successful efforts from both the observational and theoretical side, planetary nebulae still keep some of their secrets (like the widely unknown distances) and will undoubtedly also be objects of thorough investigations in the years to come.
Book Synopsis Asymmetric Planetary Nebulae VII by : Quentin A. Parker
Download or read book Asymmetric Planetary Nebulae VII written by Quentin A. Parker and published by MDPI. This book was released on 2019-03-21 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the best and most up-to-date contributions in the field of late stage stellar evolution, as presented at the APNVII conference in Hong Kong in December 2017. A total of 60 scientists from 20 countries gathered to present, listen, interact and discuss the most current issues and problems in planetary nebulae and related objects research. The emphasis of this influential series of meetings, which was the seventh occasion over the last 20 years, has always been on the hypothesized and observed physical shaping mechanisms of the ejected nebulae that have such wonderful and intriguing forms. This special Galaxies conference issue of fully refereed contributions brings together a representative compilation of the meeting presentations in paper form. It captures the current “snap shot” status of this research field in some real sense. Such proceedings are well received and can be used as a reference material by both participants and all others working in the field for years to come.

Book Synopsis Planetary Nebulae by : Stuart R. Pottasch
Download or read book Planetary Nebulae written by Stuart R. Pottasch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to give a detailed description of the planetary nebulae including the relevant astronomical observations and their interpretation. Considerable attention is given to the evolution of these objects as well as to their physical characteristics. I t is hoped that the book be useful to both advanced research workers and to students with some background in astronomy. In this regard, the book should serve as a text as well as a reference work. The many tables included are expected to be useful for both purposes. The references are generally not included in the text except for historical purposes in an effort to improve readability. References are given at the end of each chapter together with sufficient text to describe their content. No attempt has been made to make the list of references complete; on the contrary it has generally been limited to the most recent literature on the subject which in turn refers to earlier research. Again, exceptions have been made for references of historical interest.

Book Synopsis Planetary Nebulae (IAU S283) by : Arturo Manchado
Download or read book Planetary Nebulae (IAU S283) written by Arturo Manchado and published by Cambridge University Press. This book was released on 2012-10-04 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planetary nebulae play a key role in stellar evolution as an important fraction of stellar matter in the Universe goes though the asymptotic giant branch and planetary nebula phases in its lifetime. They are major contributors to the chemical enrichment of the galaxies, especially for nitrogen and carbon. They also act as multi-wavelength laboratories for understanding atomic, molecular, dust, and plasma processes in different astrophysical environments, and for studying the dynamics and mass distributions of galaxies. IAU Symposium 283 brought together experts from a variety of countries to present new results including: those from IPHAS and HERSCHEL; the detection of fullerenes in our galaxy and its neighbors; a new catalogue of about 600 planetary nebulae spectra; and the latest three-dimensional models of the common envelope phase. This volume is an essential reference for all those specializing in planetary nebulae.

Book Synopsis Planetary and Proto-Planetary Nebulae: From IRAS to ISO by : Andrea Preite Martinez
Download or read book Planetary and Proto-Planetary Nebulae: From IRAS to ISO written by Andrea Preite Martinez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two questions that we can ask ourselves in order to describe this workshop. The first question is a double question: why a conference on this subject and why a workshop? The first idea of organizing this workshop came while reading the scientific objectives of one of the instruments onboard the ISO satel lite (a phase A document concerning the IR camera). On going through the scientific motivations for building the instrument I realized with surprise that no mention was made of Planetary Nebulae (PN). At present this is no longer true. There is a chapter indicating the capabilities of the camera in the PN field and what we can reasonably expect from that instrument. But it was at this moment that the first idea of organizing a workshop on the subject of PN came. Of course there are other, stronger motivations. The first one is that I think this is the right moment after IRAS. I think we all spent the last two or three years working on IRAS data. IRAS represented a corner-stone for those working on Planetary Nebulae: the amount of data that came out of the instruments onboard the satellite was enormous and opened up new ways of looking at planetary nebulae, as well as at other fields.
Book Synopsis Planetary Nebulae in Our Galaxy and Beyond (IAU S234) by : International Astronomical Union. Symposium
Download or read book Planetary Nebulae in Our Galaxy and Beyond (IAU S234) written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2006 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planetary nebulae represent the brief transition between Asymptotic Giant Branch stars and White Dwarfs. As multi-wavelength laboratories they have played a key role in developing our understanding of atomic, molecular, dust and plasma processes in astrophysical environments. The means by which their wonderfully diverse morphologies are obtained is currently the subject of intense research, including hydrodynamical shaping mechanisms and the role of binarity, stellar magnetic fields and rotation. Their contribution to the chemical enrichment of galaxies is another very active research area, as is the ever growing use of their narrow high luminosity emission lines to probe the dynamics and mass distributions of galaxies and the intergalactic media of clusters of galaxies. IAU S234 summarises the current status of research on the properties and processes of planetary nebulae, as reported in reviews and papers by leading experts working in the field.
