Drop by if you're interested! Here's the longer description of the talk:
In Fire and In Ice : The Death of Stars
Stars live for millions or billions of years, but they don't liveforever. When a star reaches the end of its lifetime, spectactular fireworks can result. In this popular talk for interested layman, Dr. Knop will outline what it is that keeps a star together during its lifetime, and what happens to stars of various different sizes when that process finally breaks down. He'll talk about the ejection of planetary nebulae, the cooling of white dwarves, and the most spectacular of stellar events, supernovae.
