    Oxygen abundances in F-type stars of the Hyades and the Ursa Major group
    We have derived the oxygen abundances of 50 F-type main-sequence stars, belonging to the Hyades open cluster, the Ursa Major group, and the field, using an NLTE...

    Oxygen abundances in old disc and halo stars of the Galaxy
    Intermediate resolution CCD spectra of the oxygen triplet at 7770 A have been analyzed to determine oxygen abundances in a sample of metal-deficient stars with...

    Oxygen abundances in unevolved metal-poor stars - Interpretation and consequences
    The oxygen abundance has been determined by analysis of the O I infrared triplet in 30 unevolved field stars of metallicities in the range Fe/H abundance ratio...

    Phase space distribution of halo particles and detection of WIMPS
    We calculate the velocity distribution of halo particles using realistic models for the density profiles of the Galactic disk, spheroid, and halo components. We...

    Physical parameters of reflection nebulae in the galaxy
    Given observed equivalent widths of Mg II and Mg I absorptions due to an interstellar cloud in which a late-B star is embedded, it is shown that the basic...
