Spectroscopic and Photometric Observations of the Close Binary BPM 71214

Kawka, Adela; Vennes, Stephane

Description

We have obtained photometric and spectroscopic observations of the close DA plus dMe binary BPM 71214. We have updated the ephemeris of the system and observed ellipsoidal variations of the secondary star, which establishes that the red dwarf is nearly rilling its Roche lobe. Our new observations suggest that BPM 71214, along with EC 13471-1258, may belong to a new class of hibernating novae.
