Summary

"Stellar Physics" is a rather unique book in the growing literature on star formation and evolution. Not only does the author, a leading expert in the field, give a very thorough description of the current knowledge about stellar physics, but he handles with equal care the many problems that this field of research still faces. A bibliography with well over 650 entries makes this book an unparalleled source of references. "Stellar Evolution and Stability" is the second volume and can be read, as can the first volume, as a largely independent work. It traces in great detail the evolution of the protostar towards the main sequence and beyond this to the last stage of stellar evolution, with the corresponding vast range from white dwarfs to the mighty supernovae explosions and blackhole formation. The book concludes with special chapters on the dynamical, thermal and pulsing stability of stars.
