A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
Planets with radii between that of the Earth and Neptune (hereafter referred to as ‘sub-Neptunes’) are found in close-in orbits around more than half of all Sun-like stars1,2. However, their composition, formatio...

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...

The PLATO 2.0 mission
PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addresses fundamental questio...

The WASP Project and SuperWASP Camera
The WASP project and infrastructure supporting the SuperWASP Facility are described. As the instrument, reduction pipeline and archive system are now fully operative we expect the system to have a major impact...

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...

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...

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...
