This text, designed for beginning students of stellar physics, introduces the fundamentals of stellar structure and evolution. In emphasizing the general picture of the life cycles of stars and the physics responsible, it also allows prospective specialists a taste of many of the detailed aspects of this mature discipline. The authors develop a solid foundation in important theory that is often overlooked in typical courses, yet steer clear of extraneous intensive mathematics and physics. Topics include nuclear physics and stellar energy sources, the equation of state of stellar material, phenomenological approaches to convection, and modern numerical techniques for computation of stellar evolution. Keeping pace with recent developments, the authors incorporate important elements such as asteroseismology, and the effects of rotation and magnetic fields.

Rezensionen
From the reviews of the second edition: "This updated edition will be welcomed by the scientific community. ... gives an excellent general introduction to the subject. ...This book is especially suited for students in astrophysics and astronomy at the master level or starting a Ph.D. thesis, but also for post-graduate science students looking to enlarge their horizon." (Cyriel Wagemans, Physicalia, Vol. 57(3), 2005) "This book is aimed at senior undergraduate or early graduate students in astronomy ... . It provides a broad overview of the physical basics of stellar structure and evolution sufficient to whet the appetite of the student sufficiently ... . Recommended, yes, but only for serious students of stellar physics, as light reading, or a pretty picture book, it is not." (Roger Feasey, Journal of the Auckland Astronomical Society AAS, February, 2005)
