Abstract : The early low-mass, long-lived metal-poor Population II stars are formed from the enriched material left behind by the first stars. These stars preserve the chemical imprints of the gas from which they formed, provided their surface chemical composition are not altered significantly either by any internal mixing processes or by any external processes despite their old age. The chemical abundances of these stars can therefore be used to trace back the early nucleosynthesis and the astrophysical sites of their occurrence. Low mass metal-poor stars contribute significantly to the Galactic chemical enrichment and can be used as powerful tools to address a wide variety of astrophysical issues. Some results obtained from our recent studies will be discussed.
