    Secular contraction in extreme helium stars and the future of V4334 Sgr

    Speculative connections have been made between Sakurai's Object andother hydrogen-deficient stars, principally the RCB stars and [WC]central stars of planetary nebulae. RCBs have also been postulated as the pr...

    Optical Spectroscopy of V4334 Sgr: 1996–2000

    Due to a combination of rapid expansion and changes in chemical composition, the optical spectrum of V4334 Sgr changed rapidly between discovery in 1996 Februaryand extinction during 1999. As one of the most r...

    Photometric and Spectroscopic Monitoring of the SDBV Star PG 1605+072:

    A small fraction of sdB stars show short-period, multiperiodic light variations and form the new class of pulsating star known as EC 14026 variables, after the prototype, or, alternately, as sdBV stars. Until ...

    Spectroscopic Studies of the Pulsating SDB Binary PG1336-018

    The subdwarf B star PG1336-018 (=NY Vir) is a pulsating star in a very short-period (0.101 d) eclipsing binary system [4]. The secondary is thought to be a late-type dwarf of type ∼M5. The star pulsates with p...

    Serendipitous Asteroid Lightcurve Survey Using SuperWASP

    The SuperWASP project is an ultra-wide angle search for extra solar planetary transits. However, it can also serendipitously detect solar system objects, such as asteroids and comets. Each SuperWASP instrument...

    An Earth-sized exoplanet with a Mercury-like composition

    Earth, Venus, Mars and some extrasolar terrestrial planets1 have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle2. At the inner frontier of the Solar S...
