SBS 0802+529: A New Variable Star from the Second Byurakan Survey

Abstract

A new emission line star was discovered on the plates of the Second Byurakan Survey (SBS). the follow up spectroscopy demonstrated that the object had a spectrum dominated by a late-type giant star with superposed hydrogen emission lines. the object resembles a pulsating Mira, but the amplitude of variability and a rapid UV variability are quite unusual for a single star, and we tentatively classify the object as a symbiotic star.
