Formation of the Halo Stellar Population in Spiral and Elliptical Galaxies
A scenario of galactic halo formation through mergers of fragments has been considered. In the framework of the scenario sets of fragments have been obtained from the observed halo metallicity distribution function of the Milky Way Galaxy and others. Our results allow us to conclude that 1) in our Galaxy a halo field star formation can be occured in the fragments evolved as closed system 2) the formation of the bulk of halo field stars of M31 and NGC 5128 perhaps is not associated with the formation of the halo globular clusters in these galaxies 3) in our Galaxy the formation of the halo field stars could be associated with the halo globular cluster formation
