J/A+A/326/722       HIPPARCOS Ba stars     (Mennessier+ 1997)

Ba stars, galactic populations and evolution Mennessier M.O., Luri X., Figueras F., Gomez A.E., Grenier S., Torra J., North P. <Astron. Astrophys. 326, 722 (1997)> =1997A&A...326..722M (SIMBAD/NED BibCode)
ADC_Keywords: Stars, barium ; Magnitudes, absolute ; Stars, distances Keywords: stars: absolute magnitude - Ba stars - Kinematics - galactic populations - stellar evolution 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. File Summary:
