Scientific paper

Based on the assumption that the first stellar generation was formed out of massive primordial clouds, it is shown that the mean metallicity of the low-mass stars of the first stellar generation is expected to have a value similar to that of population II. Population II stars are interpreted as former members of large associations of which globular clusters are also remnants. The proposed scenario is consistent with the lack of success of finding metal-free low mass stars, the invariance of the metallicity histogram of the spherically distributed globular clusters with galactocentric distance, the paucity of G dwarfs with intermediate metallicity, and the O/Fe ratio difference in population II and in the disk population.
