The Death of Sun-Like Stars

Dr. Stacy Palen
Department of Physics

Stars like the Sun die by shedding their outer layers into a large shell known as a planetary nebula.  At one time, we thought we completely understood this process. But the improved imaging capabilities of space telescopes, and, more recently, ground-based telescopes showed that we didn't understand anything at all.  Images of these objects leave us with the question: how does a round star create a shell that is so decidedly not-round?  Dr. Palen will address recent steps forward in answering this question, along with some related research about the Sun that may connect and give insight into death of the Sun itself.
