I will present an overviw of recent work on the early chemical evolution of galaxies.
Available information on the early Milky Way
(derived from observations of abundances, abundance ratios, metallicity distributions
etc.) will be compared to information about the distant Universe (derived from e.g.
metallicity, star formation rate, supernova rates, abundance patterns, etc. as a
function...

High resolution spectroscopy for very metal-poor stars have revealed
that some fraction of objects have large excesses of neutron-capture
elements, whose abundance patterns agree very well with that of the
r-process component of solar-system material (e.g. Sneden et al. 1996,
ApJ, 467, 819). However, recent abundance studies show the existence
of objects that have quite different...

AGB stars are the nuclear production phase of low- and intermediate mass stars. The
double-shell burning of He and H around the electron degenerate core drives a rich
pattern of nucleosynthesis, including the slow neutron capture process, as well as
the formation of neutron rich isotopes. This nucleosynthesis is now observationally
accessible in extremely metal poor stars, in...
