... The metallicity distribution of disk F stars in different age ranges: the left column for the sample of stars within 80 pc around the Sun; the right column for the restored complete sample at the solar galactocentric distance with allowance made for the ...

... Then, at a given metallicity, there must be present among the late MS stars the old ones as well as young ones, whereas the early old stars have already evolved and left the MS. In this picture, G giants are the stars of the ascending red giant branch. ...
... is the straight regression for the complete restored sample; the dashed line is that for the initial sample of F stars from the solar surrounding of 80 pc (without regarding of the radial metallicity gradient and the weight cocfficients). discussion in ...
... As a result, velocity dispersion decreases with increasing metallicity for the metal-poor stars and remains essentially constant for the metal-rich stars. ...
