The size of a planet is an observable property directly connected to the physics of its formation and evolution. We used precise radius measurements from the California-Kepler Survey to study the…
WASP-12b: THE HOTTEST TRANSITING EXTRASOLAR PLANET YET DISCOVERED
- L. Hebb, A. Collier-Cameron, P. Wheatley
- Physics, Geology
- 17 December 2008
The planet has an equilibrium temperature of T eq = 2516 K caused by its very short period orbit around the hot, twelfth magnitude host star and has the largest radius of any transiting planet yet detected.

A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large Synoptic…
Line-profile tomography of exoplanet transits - II. A gas-giant planet transiting a rapidly rotating A5 star
- A. Cameron, E. Guenther, R. West
- Physics, Geology
- 26 April 2010
Photometry and time-series spectroscopy through three separate transits are used to confirm the existence of a gas-giant planet with an orbital period of 1.22 d in orbit around HD 15082, and opens the way to studying the formation of planets around a whole new class of young, early-type stars, hence under different physical conditions and generally in an earlier stage of formation than in sharp-lined late- type stars.
An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b

Either WASP-18 is in a rare, exceptionally short-lived state, or the tidal dissipation in this system (and possibly other hot-Jupiter systems) must be much weaker than in the Solar System.
WASP-19b: THE SHORTEST PERIOD TRANSITING EXOPLANET YET DISCOVERED
- L. Hebb, A. Collier-Cameron, P. Wheatley
- Physics, Geology
- 3 January 2010
We report on the discovery of a new extremely short period transiting extrasolar planet, WASP-19b. The planet has mass Mpl = 1.15 ± 0.08 MJ, radius Rpl = 1.31 ± 0.06 RJ, and orbital period P =…
CHARACTERIZING THE COOL KOIs. III. KOI 961: A SMALL STAR WITH LARGE PROPER MOTION AND THREE SMALL PLANETS
- P. Muirhead, J. Johnson, J. Lloyd
- Physics, Geology
- 10 January 2012
We characterize the star KOI 961, an M dwarf with transit signals indicative of three short-period exoplanets discovered by the Kepler mission. We proceed by comparing KOI 961 to Barnard's Star, a…
KEPLER FLARES. I. ACTIVE AND INACTIVE M DWARFS
- S. Hawley, J. Davenport, E. Hilton
- Physics
- 28 October 2014
We analyzed Kepler short-cadence M dwarf observations. Spectra from the Astrophysical Research Consortium 3.5 m telescope identify magnetically active (Hα in emission) stars. The active stars are of…
Discovery of an Unusual Dwarf Galaxy in the Outskirts of the Milky Way

- Physics
- 5 January 2007
We announce the discovery of a new dwarf galaxy, Leo T, in the Local Group. It was found as a stellar overdensity in the Sloan Digital Sky Survey Data Release 5 (SDSS DR5). The color-magnitude…
WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE
- A. Cameron, F. Bouchy, P. Wheatley
- Geology, Physics
- 25 September 2006
Using the newly commissioned radial-velocity spectrograph SOPHIE at the Observatoire de Haute-Provence, it is found that WasP-1b and WASP-2b exhibit reflex orbital radial-VELocity variations with amplitudes characteristic of planetary-mass companions and in-phase with the photometric orbits.
