A Spectroscopic View of Epsilon Aurigae

Abstract

AbstractSpectroscopic observations from the ultraviolet, visible, and infrared obtained at the recent eclipse are discussed. The rotation curve for the disk around the secondary suggests that secondary is a low mass star (or binary). This result with the known mass function suggests that the primary may be a low mass (m1 ≤ the Chandraskehar limit, 1.4 M⊙) star leaving the AGB and evolving to the white dwarf region.
