Origin of the elements
Friday 23 March 2007
at Nordita Seminar Room
Prof. Birgitta Nordström
(Lund Observatory and Copenhagen Observatory)
Big Bang produces bland distribution of H, D, 3He, 4He, and traces of Li, Be, and B isotopes.
First stars and galaxies form (poorly understood epoch)
Massive stars burn quickly and brightly. Becoming unstable, the most massive stars explode as SNe, ejecting newly synthesized elements from C to U
Ejected elements are incorporated into new generations of stars, planets, human beings, etc.
