Seminar:- Physics at the End of Stellar Evolution
Stars like the Sun end their lives by mass loss. During the late stages of their evolution, they develop an extreme wind which removes the entire envelope within 10^5 years or less. This phase is called the superwind; the physics which drives it is very poorly understood. The ejecta become visible as a planetary nebula, while the star ceases nuclear burning and enters the white dwarf cooling track. The talk will discuss the driving processes of the mass loss, the evolution of the star and nebula after the mass loss ends, and the effect of close binary interaction.
