Gaia DR2 and EDR3 data and evolutionary status of post-AGB stars with high radial velocities.

AOKI W., MATSUNO T. and PARTHASARATHY M.

Abstract (from CDS):

Using the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) data and list of post-AGB candidates, we investigate the parallax, proper motion, and binarity for 20 post-AGB stars and candidates that have high radial velocities. From their Gaia distances, their luminosities and kinematics are derived. The evolutionary status of these stars is discussed from their location on the post-AGB evolutionary tracks. Nine stars are confirmed to be post-AGB stars that have initial main-sequence masses of around one or two solar masses. From their kinematics information, two objects among them are identified to belong clearly to the halo population, suggesting low mass. We discuss the origin and evolutionary status of other objects in the sample of this work with high radial velocities.
