Single Transit Candidates from K2: Detection and Period Estimation

H. P. Osborn, D. J. Armstrong, D. J. A. Brown +9

Photometric surveys such as Kepler have the precision to identify exoplanet and eclipsing binary candidates from only a single transit. K2, with its 75d campaign duration, is ideal…

WASP-135b: a highly irradiated, inflated hot Jupiter orbiting a G5V star

Jessica J. Spake, David J. A. Brown, Amanda P. Doyle +27

We report the discovery of a new transiting planet from the WASP survey. WASP-135b is a hot Jupiter with a radius of 1.30 pm 0.09 Rjup, a mass of 1.90 pm 0.08 Mjup and an orbital p…

The Host Stars of Keplers Habitable Exoplanets: Superflares, Rotation and Activity

D. J. Armstrong, C. E. Pugh, A. -M. Broomhall +4

We embark on a detailed study of the lightcurves of Keplers most Earth-like exoplanet host stars using the full length of Kepler data. We derive rotation periods, photometric activ…

Photo-dynamical mass determination of the multi-planetary system K2-19

S. C. C. Barros, J. M. Almenara, O. Demangeon +32

K2-19 is the second multi-planetary system discovered with K2 observations. The system is composed of two Neptune size planets close to the 3:2 mean-motion resonance. To better cha…

Insights into internal effects of common-envelope evolution using the extended Kepler mission

J. J. Hermes, B. T. Gaensicke, A. Bischoff-Kim +14

We present an analysis of the binary and physical parameters of a unique pulsating white dwarf with a main-sequence companion, SDSS J1136+0409, observed for more than 77 d during t…

One of the closest exoplanet pairs to the 3:2 Mean Motion Resonance: K2-19b \& c

David J. Armstrong, Alexandre Santerne, Dimitri Veras +25

The K2 mission has recently begun to discover new and diverse planetary systems. In December 2014 Campaign 1 data from the mission was released, providing high-precision photometry…

K2 Variable Catalogue: Variable Stars and Eclipsing Binaries in K2 Campaigns 1 and 0

D. J. Armstrong, J. Kirk, K. W. F. Lam +6

We have created a catalogue of variable stars found from a search of the publicly available K2 mission data from Campaigns 1 and 0. This catalogue provides the identifiers of 8395…
