Transits and starspots in the WASP-6 planetary system
Jeremy Tregloan-Reed, John Southworth, M. Burgdorf +27
We present updates to \textsc{prism}, a photometric transit-starspot model, and \textsc{gemc}, a hybrid optimisation code combining MCMC and a genetic algorithm. We then present hi…
Transits and starspots in the WASP-19 planetary system
Jeremy Tregloan-Reed, John Southworth, C. Tappert
We have developed a new model for analysing light curves of planetary transits when there are starspots on the stellar disc. Because the parameter space contains a profusion of loc…
Discovery and Mass Measurements of a Cold, 10-Earth Mass Planet and Its Host Star
Y. Muraki, C. Han, D. P. Bennett +125
We present the discovery and mass measurement of the cold, low-mass planet MOA-2009-BLG-266Lb, made with the gravitational microlensing method. This planet has a mass of m_p = 10.4…
MOA-2009-BLG-387Lb: A massive planet orbiting an M dwarf
Virginie Batista, A. Gould, S. Dieters +25
We report the discovery of a planet with a high planet-to-star mass ratio in the microlensing event MOA-2009-BLG-387, which exhibited pronounced deviations over a 12-day interval,…
A sub-Saturn Mass Planet, MOA-2009-BLG-319Lb
N. Miyake, T. Sumi, Subo Dong +119
We report the gravitational microlensing discovery of a sub-Saturn mass planet, MOA-2009-BLG-319Lb, orbiting a K or M-dwarf star in the inner Galactic disk or Galactic bulge. The h…
High-precision photometry by telescope defocussing. III. The transiting planetary system WASP-2
John Southworth, L. Mancini, S. Calchi Novati +23
We present high-precision photometry of three transits of the extrasolar planetary system WASP-2, obtained by defocussing the telescope, and achieving point-to-point scatters of be…
Physical properties of the 0.94-day period transiting planetary system WASP-18
John Southworth, T. C. Hinse, M. Dominik +24
We present high-precision photometry of five consecutive transits of WASP-18, an extrasolar planetary system with one of the shortest orbital periods known. Through the use of tele…
