Book excerpt: The rotation and magnetic evolution of stars is examined in detail. Advection of angular momentum by convective plumes is a source of differential rotation, which both reduces the angular momentum loss to stellar winds and spins up the inner regions. This spin up not only affects the rotation of the stellar remnant, but also facilitates the winding of magnetic field lines necessary to amplify a seed field. In radiative regions we demonstrate that an embedded magnetic field can effectively mix angular momentum, as well as sustain coupling with adjacent convective zones. In addition to the resulting angular momentum transport model, we consider a mechanism for rotationally-induced winding of a seed magnetic field. When this mechanism operates at a convective-radiative boundary which moves in a Lagrangian sense towards the convection zone, net helicity is left behind in the newly radiative material. We employ this model of angular momentum transport and helicity deposition in stellar models of a wide range of masses. Our aim is to gauge the effect on the evolution of rotation and the impact on the properties of stellar remnants. In low- and intermediate-mass stars we find a quantitative agreement between the predicted and observed core and surface rotation rates, during both the sub-giant and helium-burning phases. Continuing the evolution to the ejection of the envelope, we are able to reproduce the spin periods and magnetic fields of highly magnetic white dwarf remnants. We find similar success in massive stellar models, by being able to reproduce both the spin periods and magnetic fields of pulsars. And in progenitors of black holes with sufficiently high angular momentum pre-core-collapse, a portion of the infalling material can reach rotational support. This quenches the accretion onto the newly formed black hole, and may result in observable phenomena, such as high energy jets.

Book excerpt: Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the universe has changed dramatically during the course of the last few decades. The fields of astronomy and astrophysics are making new connections to physics, chemistry, biology, and computer science. Based on a broad and comprehensive survey of scientific opportunities, infrastructure, and organization in a national and international context, New Worlds, New Horizons in Astronomy and Astrophysics outlines a plan for ground- and space- based astronomy and astrophysics for the decade of the 2010's. Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise including technological development, theory, computation and data handling, laboratory experiments, and human resources. New Worlds, New Horizons in Astronomy and Astrophysics proposes enhancing innovative but moderate-cost programs in space and on the ground that will enable the community to respond rapidly and flexibly to new scientific discoveries. The book recommends beginning construction on survey telescopes in space and on the ground to investigate the nature of dark energy, as well as the next generation of large ground-based giant optical telescopes and a new class of space-based gravitational observatory to observe the merging of distant black holes and precisely test theories of gravity. New Worlds, New Horizons in Astronomy and Astrophysics recommends a balanced and executable program that will support research surrounding the most profound questions about the cosmos. The discoveries ahead will facilitate the search for habitable planets, shed light on dark energy and dark matter, and aid our understanding of the history of the universe and how the earliest stars and galaxies formed. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public.

Available in PDF, EPUB and Kindle. Book excerpt: Binarity is an important factor affecting the evolution of a star. The fundamental properties of a star such as mass, rotation rate, magnetic field, lifetime and the end-product are strongly influenced by binary parameters and their evolution. Most of the massive stars, which undergo a supernova explosion in the end of their lives, reside in close binary systems in which the components experience mass transfer or mass loss. Therefore, during their evolution, their stellar parameters are significantly altered. This also affects the type of the supernova they experience as well as the type of their compact stellar remnants, neutron stars and black holes. By disrupting the gravitational bound of the system, the supernova leaves the companion as a runaway star which shows a high space velocity owing to its former orbital motion. The distribution of binary system mass ratios shows that the pre-supernova companion should also be a massive or an intermediate mass star. Although many massive runaway stars have been found so far, none of them could be linked to a supernova remnant or a neutron star with high accuracy. Thus, their origins are doubtful. By finding massive runaway stars which can be associated to a supernova remnant and a neutron star, firstly, the theoretical case of binary supernova ejection of a star can be proven. Secondly, the relation between the binary evolution and the observational properties of neutron stars and supernova remnants can be found. Thirdly, the effects of the binary evolution on the stellar parameters of the pre-supernova companion can be identified. Lastly, the supernova remnant parameters such as distance and age can be determined more precisely.

Available in PDF, EPUB and Kindle. Book excerpt: Every atom of our bodies has been part of a star. Our very own star, the Sun, is crucial to the development and sustainability of life on Earth. This Very Short Introduction presents a modern, authoritative examination of how stars live, producing all the chemical elements beyond helium, and how they die, sometimes spectacularly, to end as remnants such as black holes. Andrew King shows how understanding the stars is key to understanding the galaxies they inhabit, and thus the history of our entire Universe, as well as the existence of planets like our own. King presents a fascinating exploration of the science of stars, from the mechanisms that allow stars to form and the processes that allow them to shine, as well as the results of their inevitable death. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Available in PDF, EPUB and Kindle. Book excerpt: This book invites the reader to understand our Universe, not just marvel at it. From the clock-like motions of the planets to the catastrophic collapse of a star into a black hole, gravity controls the Universe. Gravity is central to modern physics, helping to answer the deepest questions about the nature of time, the origin of the Universe and the unification of the forces of nature. Linking key experiments and observations through careful physical reasoning, the author builds the reader's insight step-by-step from simple but profound facts about gravity on Earth to the frontiers of research. Topics covered include the nature of stars and galaxies, the mysteries of dark matter and dark energy, black holes, gravitational waves, inflation and the Big Bang. Suitable for general readers and for undergraduate courses, the treatment uses only high-school level mathematics, supplemented by optional computer programs, to explain the laws of physics governing gravity.
