Late Stages of Stars, Supernovae and Gamma-ray Bursts

In this course you will study fundamental processes governing the final stages of the stellar life cycle, and how some stars end as supernova explosions and gamma-ray bursts.

Through this course you will develop an understanding of the fundamental processes governing the evolution of stars in their dramatic late stages. While the sun and other light stars only burn hydrogen and helium, and end as white dwarfs, more massive stars continue nuclear fusion until an iron core is formed. You will learn what such stars look like, and what different outcomes are possible once the nuclear fuel is eventually exhausted. This depends on a variety of physical processes such as how the star loses mass by stellar winds, and how neutrinos first cool and then sometimes explode the core. You will study how different elements are made in supernova explosions and gamma-ray bursts, and how neutron stars and black holes are born.
