Description:
HIPPARCOS astrometric and kinematical data together with radial
velocities from other sources are used to calibrate both luminosity
and kinematics parameters of Ba stars and to classify them. Five
distinct classes have been found i.e. some halo stars (H) and four
groups belonging to disk population: roughly super-giants (S), two
groups of giants (one on the giant branch (G), the other at the clump
location(C)) and dwarfs (D). Individual distances and luminosities
are estimated.
