Possible detection of a bimodal cloud distribution in the atmosphere of HAT-P-32\,A\,b from multi-band photometry
Jeremy Tregloan-Reed, John Southworth, L. Mancini +6
We present high-precision photometry of eight separate transit events in the HAT-P-32 planetary system. One transit event was observed simultaneously by two telescopes of which one…
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…
Multi-filter transit observations of WASP-39b and WASP-43b with three San Pedro Mártir telescopes
D. Ricci, F. G. Ramón-Fox, C. Ayala-Loera +6
Three optical telescopes located at the San Pedro Mártir National Observatory were used for the first time to obtain multi-filter defocused photometry of the transiting extrasolar…
OGLE-2011-BLG-0265Lb: a Jovian Microlensing Planet Orbiting an M Dwarf
J. Skowron, I. -G. Shin, A. Udalski +121
We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265. Such a system is very rare among known planet…
Automated differential photometry of TAOS data: preliminary analysis
D. Ricci, P. -G. Sprimont, C. Ayala +8
A preliminary data analysis of the stellar light curves obtained by the robotic telescopes of the TAOS project is presented. We selected a data run relative to one of the stellar f…
High-precision photometry by telescope defocussing. VI. WASP-24, WASP-25 and WASP-26
John Southworth, T. C. Hinse, M. Burgdorf +55
We present time-series photometric observations of thirteen transits in the planetary systems WASP-24, WASP-25 and WASP-26. All three systems have orbital obliquity measurements, W…
MOA-2010-BLG-328Lb: a sub-Neptune orbiting very late M dwarf ?
K. Furusawa, A. Udalski, T. Sumi +119
We analyze the planetary microlensing event MOA-2010-BLG-328. The best fit yields host and planetary masses of Mh = 0.11+/-0.01 M_{sun} and Mp = 9.2+/-2.2M_Earth, corresponding to…
High-precision photometry by telescope defocussing. V. WASP-15 and WASP-16
J. Southworth, L. Mancini, P. Browne +40
We present new photometric observations of WASP-15 and WASP-16, two transiting extrasolar planetary systems with measured orbital obliquities but without photometric follow-up sinc…
Physical properties, transmission and emission spectra of the WASP-19 planetary system from multi-colour photometry
L. Mancini, S. Ciceri, G. Chen +43
We present new ground-based, multi-colour, broad-band photometric measurements of the physical parameters, transmission and emission spectra of the transiting extrasolar planet WAS…
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…
High-precision photometry by telescope defocussing. IV. Confirmation of the huge radius of WASP-17b
John Southworth, M Dominik, X-S Fang +29
We present photometric observations of four transits in the WASP-17 planetary system, obtained using telescope defocussing techniques and with scatters reaching 0.5 mmag per point.…
OGLE-2008-BLG-510: first automated real-time detection of a weak microlensing anomaly - brown dwarf or stellar binary?
V. Bozza, M. Dominik, N. J. Rattenbury +103
The microlensing event OGLE-2008-BLG-510 is characterised by an evident asymmetric shape of the peak, promptly detected by the ARTEMiS system in real time. The skewness of the ligh…
A much lower density for the transiting extrasolar planet WASP-7
John Southworth, M. Dominik, U. G. Jorgensen +29
We present the first high-precision photometry of the transiting extrasolar planetary system WASP-7, obtained using telescope defocussing techniques and reaching a scatter of 0.68…
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…
