Chemical Evolution of the Galaxy

Annual Review of Astronomy and Astrophysics, 1991
Since the discovery of the cosmic microwave background ( 1 84), it is gen­ erally assumed that the universe originated from a hot big bang (78). Detailed nucleosynthesis calculations based on the hot big bang model (e.g. 4, 1 82, 221 ) showed that no element heavier than 9Be could have been synthesized primordially with an abundance exceeding 101 4 by ...

Chemical Evolution of Galaxies

Annual Review of Astronomy and Astrophysics, 1976
The various nucleosynthetic processes needed to account for the formation of the different nuclear species have been described in the previous chapters as well as the location of these nucleosynthetic events. At the beginning of this monograph, the evolution of the matter which constitutes the celestial bodies such as planets, stars and galaxies was ...

Chemical Evolution of Galaxies

1987
We review some of the present ideas on chemical evolution of irregular galaxies and disks of spiral galaxies. Based on the O abundances in stars and H II regions we present a discussion of the yield; we also discuss the effects of large scale mass flows and of cold dark matter to explain variations in the observed yield. The C, N, O observed abundances
