2019IBVS.6258....1P - IAU Inform. Bull. Var. Stars, 6258, 1-1 (2019)
Distance, Luminosity and evolutionary status of epsilon Aurigae (F0Iaep) from Gaia DR2 parallax.
PARTHASARATHY M. and MUNEER S.
Abstract (from CDS):
From Gaia DR2 parallax of epsilon Aurigae the distance, Mv, Mbol, and log(L*/LMsun) are found to be 445 parsecs, -6.5 mag, -6.5 mag, and 4.5 respectively. These results clearly indicate that epsilon Aurigae (F0Iae) is post-AGB star. The progenitor of epsilon Aurigae is most likely an intermediate mass star of 4 to 5 solar masses or the progenitor may be a star which is lower limit of a super-AGB star.
