Teised raamatud teemal:
The study of stellar dynamics is experiencing an exciting new wave of interest thanks to observational campaigns and the ready availability of powerful computers. Whilst its relevance includes many areas of astrophysics, from the structure of the Milky Way to dark matter halos, few texts are suited to advanced students. This volume provides a broad overview of the key concepts beyond the elementary level, bridging the gap between the standard texts and specialist literature. The author reviews Newtonian gravity in depth before examining the dynamical properties of collisional and collisionless stellar-dynamical systems that result from gravitational interactions. Guided examples and exercises ensure a thorough grounding in the mathematics, while discussions of important practical applications give a complete picture of the subject. Readers are given a sound working knowledge of the fundamental ideas and techniques employed in the field and the conceptual background needed to progress to more advanced graduate-level treatises.

Stellar dynamics plays an important role in many areas of astrophysics. This text bridges the gap between the standard texts and specialist literature on the topic. Ideal for advanced students, fundamental ideas and techniques are explored thoroughly to give a strong grounding for exploring the subject further.

Arvustused

'This text is notable for its clarity and rigour. It would be perfect for a course directed at mathematically-minded students, from the second year of undergraduate study on, and individuals could use it for self-study This is also a scholarly book. The literature is extensively, yet selectively, cited from recent times right back to the 18th Century as appropriate Hence the book will make it easy for a newcomer to the eld to progress to the research frontier.' James Binney, The Observatory 'The book may be of some value to libraries that support students of astrophysics at the graduate and very advanced undergraduate levels Recommended.' T. Barker, Choice Magazine

Luca Ciotti is Professor of Astronomy and Astrophysics at the University of Bologna, where he has also served for many years as Director of the Collegio Superiore. Since 1992 he has been a long-term visitor of the Princeton University Observatory. His work developed in several fields of theoretical astrophysics, with main interests in stellar dynamics, fluid dynamics, and black hole accretion. This is his second book in the field, having previously written Lecture Notes on Stellar Dynamics (2001) based on the lectures given at the Scuola Normale Superiore in Pisa.
