Twinkle, Twinkle, Exploding Star, How We Wonder What You Are!
Supernovae are the spectacular explosions that signal violent stellar deaths. These fascinating events involve many branches of physics and are some the most powerful explosions observed in the cosmos. Supernovae produce and disseminate heavy nuclei, trigger star formation, and some cases are the birthplace of interesting astrophysical objects such as pulsars and black holes.
In the next of the popular series Astronomy Open Night, Prof. Alan Calder will discuss supernovae and his research into modeling these explosions. He will describe the classification of supernovae, proposed mechanisms for the explosions, and the physics involved in these events.
Prof. Calder joined the Stony Brook Physics and Astronomy department in 2007 after research appointments at the University of Illinois and the University of Chicago. His research is in numerically modeling astrophysical phenomena, and he has studied core collapse and thermonuclear supernovae, coalescing neutron stars, and classical novae.
