HS 2237+8154: A New Pre-CV just above the Period Gap
2004
International Astronomical Union Colloquium
Preserved Fulltext
We report follow-up observations of the new pre-cataclysmic variable HS 2237+8154, identified from the Hamburg Quasar Survey. The orbital period derived from ellipsoidal modulation observed in the iR-band as well as from the Hα radial velocity variation is orb = 178.10 ± 0.08 min. We briefly discuss the evolutionary state of this system.
