Origin of the elements
   Astrobiology

Friday 23 March 2007
from 16:00 to 17:00
at Nordita Seminar Room
Speaker : Prof. Birgitta Nordström (Lund Observatory and Copenhagen Observatory)
Abstract :
  • 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.
