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.

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.

The diverse forms that stars assume in the course of their lives can all be derived from the initial conditions: the mass and the original chemical composition. In this textbook the basic concepts of stellar structure and the main roads of stellar evolution are described. The authors aim at reaching an understanding of stars and their evolution by both graduate students and astronomers who are not themselves investigating stars. Ample references to specialised review articles as well as to relevant research papers are included.

The main objective of this volume is to discuss the physical properties, observational signals and various probes of compact objects in the Universe. These include black holes, neutron stars, and exotic objects studied in alternative theories of gravity. The text is mainly addressed to postgraduate students and young researchers with the aim of introducing them to these very challenging topics.
