In Stellar Evolution Physics, Icko Iben describes the microscopic physics operating in stars and how stars respond macroscopically, showing the intricate interplay between these processes. Volume 1, intended for graduate students with a solid background in physics, covers the processes up to the onset of helium burning. Volume 2 builds on these principles, covering models of low and intermediate mass stars, the AGB phase, the final cooling white dwarf phase and a model for a massive star. Particular attention is given to the gravothermal responses to nuclear reaction-induced transformations in the interior and energy loss from the surface, responses at the heart of stellar evolution. The volumes include over 600 illustrations and many numerical solutions in order to prepare the reader to program and calculate evolutionary models for themselves. Taken together, the two volumes will prepare a graduate student for professional-level research in this key area of astrophysics.
