A New, Bright, Short-Period, Emission Line Binary in Ophiuchus
M. A. Stark, Richard A. Wade, John R. Thorstensen +4
The 11th magnitude star LS IV -08 3 has been classified previously as an OB star in the Luminous Stars survey, or alternatively as a hot subdwarf. It is actually a binary star. We…
New Ultraviolet Observations of AM CVn
Richard A. Wade, Michael Eracleous, Helene M. L. G. Flohic
We have obtained observations of the ultraviolet spectrum of AM CVn, an ultra-short-period helium cataclysmic variable, using the Space Telescope Imaging Spectrograph (STIS) aboard…
Searching for the "Missing" PG Hot Subdwarfs in SDSS and GALEX Data
Richard A. Wade, M. A. Stark, R. F. Green +1
Many EHB stars have been found in short-period binaries, where the companions in these post-common envelope systems are either white dwarfs or dM stars; these systems are catalogue…
Disentangling Composite Spectrum Hot Subdwarfs
M. A. Stark, Richard A. Wade
We give preliminary results from a spectroscopic study of composite spectrum hot subdwarfs (sd+late-type). We obtained spectra of a sample of hot subdwarfs selected from the "Catal…
Are All Hot Subdwarf Start in Close Binaries?
Richard A. Wade, M. A. Stark
We discuss whether the hypothesis that "all (or most) subdwarfs are in close binaries" is supported by the frequently reported observations of photometrically or spectroscopically…
Single and Composite Hot Subdwarf Stars in the Light of 2MASS All-Sky Photometry
M. A. Stark, Richard A. Wade, G. B. Berriman
Utilizing the Two Micron All Sky Survey (2MASS) All-Sky Data Release Catalog, we have retrieved useful near-IR J, H, and Ks magnitudes for more than 800 hot subdwarfs (sdO and sdB…
