Lecture 33: The Deaths of Stars


Listen Later

What happens to a star when it runs out of hydrogen in its core? This
lecture describes the post main-sequence evolution of stars. What
happens depends on the star's mass. Low mass stars swell up into Red
Giants, and eventually shed their envelopes and end their lives as white
dwarf stars. High mass stars become Red Supergiants, and if large
enough, end their lives in a spectacular supernova explosion that leaves
behind a neutron star or black hole. The explosion itself creates
massive quantities of heavy elements, which then seed interstellar space
with metals to be incorporated into subsequent generations of stars.
Recorded live on 2009 Nov 12 in Room 1005 Smith Laboratory on the
Columbus campus of The Ohio State University.
