Discovery of the closest hot subdwarf binary with white dwarf companion
S. Geier, T. R. Marsh, B. H. Dunlap +13
We report the discovery of an extremely close, eclipsing binary system. A white dwarf is orbited by a core He-burning compact hot subdwarf star with a period as short as $\simeq0.0…

Anne M. Archibald, Ingrid H. Stairs, Scott M. Ransom +15
Radio pulsars with millisecond spin periods are thought to have been spun up by transfer of matter and angular momentum from a low-mass companion star during an X-ray-emitting phas…
Two New Variable Hot DQ Stars
B. N. Barlow, B. H. Dunlap, R. Rosen +1
We have discovered periodic variations in the light curves of two hot DQ stars from the Sloan Digital Sky Survey, SDSS J220029.08-074121.5 and SDSS J234843.30-094245.3. These are t…
