This book aims at providing an accessible, and yet comprehensive and self-contained discussion of compact stars. After a pedagogical introduction to the physics of white dwarfs, the bulk of the book is devoted to the analysis of the structure and dynamics of neutron stars. A great deal of emphasis is placed on the dynamical models underlying the description of neutron star matter at microscopic level. The analysis of these models is inherently cross-disciplinary - from nuclear and particle physics to astrophysics and condensed matter physics and the relevant concepts are introduced following a didactic approach, drawing largely on the historical development of the field. The impact of the latest experimental data, such as gravitational waves emissions, and the potential of future observational developments in the new era of multimessenger astronomy are extensively discussed. This volume is intended to provide PhD students in physics and astrophysics with solid foundations for their future research career. It is also a useful tool for the broader audience of more advanced readers, working in the fields of nuclear and particle physics as well as gravitational physics.

This self-contained introduction to compact star physics explains important concepts from areas such as general relativity, thermodynamics, statistical mechanics, and nuclear physics. Containing many tested exercises, and written by an international expert in the research field, the book provides important insights on the basic concepts of compact stars, discusses white dwarfs, neutron stars, quark stars and exotic compact stars. Included are sections on astrophysical observations of compact stars, and present and future terrestrial experiments related to compact stars physics, as the study of exotic nuclei and relativistic heavy-ion collisions. Major developments in the field such as the discovery of massive neutron stars, and a discussion of the recent gravitational wave measurement of a neutron star merger are also presented. This book is ideal for graduate students and researchers working on the physics of compact stars, general relativity and nuclear physics.

What evidence is there for and against unified schemes for active galactic nuclei (AGN)? How do the AGN populations evolve over cosmological timescales? And what can the variability of their UV and X-ray emission tell us? These are just some of the exciting issues addressed in this volume of papers collected from the 33rd Herstmonceux conference in Cambridge. AGN are among the most spectacular objects known to astronomy. Yet, despite years of intense and wide-ranging research, the debate continues - what is their fundamental source of power? Rapid progress has been made towards answering this question by a variety of large-scale, multi-wavelength monitoring campaigns and the latest generation of satellite-borne observations. This volume provides a valuable overview and timely update of the exciting and rapidly developing field of AGN research - essential reading for graduate students and researchers.

On sait depuis longtemps que les étoiles sont des astres semblables au Soleil ; mais ce n'est qu'en 1810 que l'on a vu qu'elles sont faites de gaz incandescent. À partir de 1860, on a déterminé progressivement la composition chimique de ce gaz. Vers 1940, on a enfin compris que l'énergie des étoiles était thermonucléaire, et su comment elles la rayonnaient. Quant à leur évolution, elle a fait depuis cette époque l'objet d'une quête progressive que l'on peut considérer comme à peu près terminée. Enfin, ce n'est que tout récemment que l'on a commencé à comprendre comment les étoiles se forment à partir de la matière interstellaire et comment a lieu la mort violente des étoiles massives. Les étoiles doubles serrées sont le siège de phénomènes extraordinaires que l'on n'a pas fini d'explorer. Le présent ouvrage fait le point sur tous ces aspects, tandis que l'impact de l'évolution des étoiles sur celle des galaxies est également abordé. Les observations les plus intéressantes sont rappelées, illustrées par des images souvent spectaculaires, tandis que la théorie est expliquée de façon simple, sans cependant éviter quelques développements mathématiques et physiques lorsqu'ils sont indispensables à une compréhension réelle des phénomènes. Ainsi, sans être un traité pour spécialistes, ce livre sera lu avec profit par les personnes qui possèdent des bases scientifiques du niveau de la licence, et qui veulent s'initier en profondeur au monde fascinant des étoiles.

In the past, they were recognized as the most destructive force in nature. Now, following a cascade of astonishing discoveries, supermassive black holes have undergone a dramatic shift in paradigm. Astronomers are finding out that these objects may have been critical to the formation of structure in the early universe, spawning bursts of star formation, planets, and even life itself. They may have contributed as much as half of all the radiation produced after the Big Bang, and as many as 200 million of them may now be lurking through the vast expanses of the observable cosmos. In this elegant, non-technical account, Melia conveys for the general reader the excitement generated by the quest to expose what these giant distortions in the fabric of space and time have to say about our origin and ultimate destiny.
