Abstract:
We reviewed the recent progress in the field of stellar/galactic
archeology, which is a study of the relics from the early galaxy. The oldest
and most pristine objects that can be observed in the galaxy are the low
mass metal poor stars of the Milky Way. They were formed during the
early phases, when the ISM might have been polluted only by the Pop-III
supernovae. With the recent large spectroscopic surveys (e.g. HK survey
by Beers and collaborators, the Hamburg-ESO survey by Christlieb and
collaborators and Sloan Digital Sky Survey) it has been possible to get
clues on the nature of the first stars that has contributed to the heavy
elements. Most of these metal-poor low mass stars also retain their signature
of the early dynamical evolution of the galaxy, which can be studied
through their orbits around the galaxy and spatial distribution. Here, we
discuss the connection between the chemical and the kinematical properties
of metal-poor stars in order to probe the early galaxy formation. We
also discuss about the globular clusters, the satellite galaxies around the
Milky Way and its possible contribution to the formation of the galaxy
halo.
