Two Earth-sized planets orbiting Kepler-20
Francois Fressin, Guillermo Torres, Jason F. Rowe +33
Since the discovery of the first extrasolar giant planets around Sun-like stars, evolving observational capabilities have brought us closer to the detection of true Earth analogues…
Kepler-22b: A 2.4 Earth-radius Planet in the Habitable Zone of a Sun-like Star
William J. Borucki, David G. Koch, Natalie Batalha +80
A search of the time-series photometry from NASA's Kepler spacecraft reveals a transiting planet candidate orbiting the 11th magnitude G5 dwarf KIC 10593626 with a period of 290 da…
The long term optical behaviour of helium accreting AM CVn binaries
Gavin Ramsay, Thomas Barclay, Danny Steeghs +4
We present the results of a two and a half year optical photometric monitoring programme covering 16 AM CVn binaries using the Liverpool Telescope on La Palma. We detected outburst…
Spin-Orbit Alignment for the Circumbinary Planet Host Kepler-16A
Joshua N. Winn, Simon Albrecht, John Asher Johnson +31
Kepler-16 is an eccentric low-mass eclipsing binary with a circumbinary transiting planet. Here we investigate the angular momentum of the primary star, based on Kepler photometry…
New short period stellar pulsators at large Galactocentric distances
Gavin Ramsay, Ralf Napiwotzki, Thomas Barclay +3
We report the discovery of 31 blue, short period, pulsators made using data taken as part of the Rapid Temporal Survey (RATS). We find they have periods between 51-83 mins and full…
Stellar variability on time-scales of minutes: results from the first 5 years of the Rapid Temporal Survey (RATS)
Thomas Barclay, Gavin Ramsay, Pasi Hakala +4
The Rapid Temporal Survey (RATS) explores the faint, variable sky. Our observations search a parameter space which, until now, has never been exploited from the ground. Our strateg…
