Evolutionary Status of Selected Post-AGB Single and Binary Stars in Gaia DR3.

PARTHASARATHY M., KOUNKEL M. and STASSUN K.G.

Abstract (from CDS):

Gaia data is helping to further understand the evolutionary status of post-AGB and related stars. In this paper we present an analysis of Gaia DR3 data of post-AGB stars and post-AGB binaries with accurate parallaxes. Gaia DR3 data of 44 post-AGB candidates are analyzed, including 16 post-AGB binary candidates. Of these, 19 stars have RUWE values >1.4. For several stars, the calculated absolute luminosities confirm that they are indeed in post-AGB evolutionary stage. We find that 12 stars have relatively lower luminosities; some of them may be post-RGB stars and some may be post-HB stars. We find that IRAS 01427+4633 (BD+46 442), IRAS 16230-3410, and IRAS 19199+3950 (HP Lyr) are evolved high velocity stars.
