From Black Clouds To Black Holes [PDF ebook] 

This book describes in a non-technical language, one of the success stories of modern (twentieth-century) astronomy. It presents us with the physical picture of what constitutes a star, with a description of how a star evolves with time, how its shape and brightness change, how it manufactures the chemical elements deep in its interior, what makes it explode. The presentation also includes exotic objects such as supernovae, pulsars, neutron stars and white dwarfs, and of course, black holes. The book will be appropriate as supplementary material for an elementary course on astronomy and astrophysics.
