Abstract:
Several samples of nearby stars with the most accurate astrometric and
photometric parameters are searched for clues to their evolutionary
history. The main samples are (1) the main-sequence stars with b-y
between 0.29 and 0.59mag (F3 to K1) in the Yale parallax catalog, (2)
a group of high-velocity subgiants studied spectroscopically by Ryan &
Lambert (1995AJ....109.2068R 1995AJ....109.2068R), and (3) high-velocity main-sequence
stars in the extensive investigation by Norris, Bessel, & Pickles
(1985ApJS...58..463N 1985ApJS...58..463N). The major conclusions are as follows: (1) The
oldest stars (halo), t≥10-12Gyr, have V-velocities (in the direction
of Galactic rotation and referred to the Sun) in the range from about
-50 to -800km/s and have a heavy-element abundance [Fe/H] of less than
about -0.8dex. The age range of these objects depends on our knowledge
of globular cluster ages, but if age is correlated with V-velocity,
the youngest may be M22 and M28 (V~-50km/s) and the oldest NGC 3201
(V~-500km/s) and assorted field stars. (2) The old disk population
covers the large age range from about 2Gyr (Hyades, NGC 752) to 10 or
12Gyr (Arcturus group, 47 Tuc), but the lag (V) velocity is restricted
to less than about 120km/s and [Fe/H]≥-0.8 or -0.9dex. The
[Fe/H]~-0.8dex division between halo and old disk, near t∼10-12Gyr, is
marked by a change in the character of the CN index (Cm) and of the
blanketing parameter K of the DDO photometry. (3) The young disk
population, t<2Gyr, is confined exclusively to a well-defined area of
the (U, V) velocity plane. The age separating young and old disk stars
is also that separating giant evolution of the Hyades (near
main-sequence luminosity) and M67 (degenerate helium cores and a large
luminosity rise) kinds. The two disk populations are also separated by
such indexes as the g-index of Geveva photometry. There appears to be
no obvious need to invoke exogeneous influences to understand the
motion and heavy-element abundance distributions of the best-observed
stars near the Sun. Individual stars of special interest include the
parallax star HD 55575, which may be an equal-component binary, and
the high-velocity star HD 220127, with a well-determined space
velocity near 1000km/s.
