This book consists of two titles, which are the following:

Stellar Evolution - Stellar evolution refers to the process by which a star changes over the course of time. This field of astrophysics studies the formation, life, and death of stars, which involves a series of complex physical processes and transformations. Here, we outline the key stages and concepts in stellar evolution.

Supernovae - Supernovae are incredibly powerful explosions that occur at the end of a star's life cycle, during which the star undergoes a dramatic increase in brightness, often outshining an entire galaxy for a brief period. They can occur through various mechanisms, such as the collapse of massive stars or the thermonuclear explosions of white dwarfs in binary systems. Supernovae play a crucial role in the evolution of galaxies, as they distribute heavy elements and trigger the formation of new stars and planetary systems.
