Tregloan-Reed, J., Southworth, J., Mancini, L., Mollière, P., Ciceri, S., Bruni, I., …Henning, T. (2018). Possible detection of a bimodal cloud distribution in the atmosphere of HAT-P-32 A b from multiband photometry. Monthly Notices of the Royal Astronomical Society, 474(4), 5485 - 5499. https://doi.org/10.1093/mnras/stx3147

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 obtained a simultaneous multiband light curve in three optical bands,...

We announce the detection of recurring sets of recurring starspot occultation events in the short-cadence K2 light curve of Qatar-2, a K dwarf star transited every 1.34 d by a hot Jupiter. In total, we detect 34 individual starspot occultation events... Read More about Recurring sets of recurring starspots on exoplanet-host Qatar-2.

Context. The orbital obliquity of planets with respect to the rotational axis of their host stars is a relevant parameter for the characterization of the global architecture of planetary systems and a key observational constraint to discriminate betw...

Starspots on WASP-107 and pulsations of WASP-118 (2017)
Journal Article
Močnik, T., Hellier, C., Anderson, D., Clark, B., & Taylor, J. (2017). Starspots on WASP-107 and pulsations of WASP-118. Monthly Notices of the Royal Astronomical Society, 469(2), 1622 - 1629. https://doi.org/10.1093/mnras/stx972

By analysing the K2 short-cadence photometry, we detect starspot occultation events in the light curve of WASP-107, the host star of a warm-Saturn exoplanet. WASP-107 also shows a rotational modulation with a period of 17.5 ± 1.4 d. Given that the ro... Read More about Starspots on WASP-107 and pulsations of WASP-118.

We report the discovery of Qatar-3b, Qatar-4b, and Qatar-5b, three new transiting planets identified by the Qatar Exoplanet Survey. The three planets belong to the hot Jupiter family, with orbital periods of ${P}_{{\rm{Q}}3{\rm{b}}}$ = 2.50792 days,... Read More about Qatar Exoplanet Survey : Qatar-3b, Qatar-4b, and Qatar-5b.

Detection of the Atmosphere of the 1.6 M ? Exoplanet GJ 1132 b (2017)
Journal Article

Detecting the atmospheres of low-mass, low-temperature exoplanets is a high-priority goal on the path to ultimately detecting biosignatures in the atmospheres of habitable exoplanets. High-precision HST observations of several super-Earths with equil... Read More about Detection of the Atmosphere of the 1.6 M ? Exoplanet GJ 1132 b.

Context. Massive stars are important building blocks of the Universe, and their stellar structure and evolution models are fundamental cornerstones of various fields in modern astrophysics. The precision of these models is strongly limited by our lac... Read More about Signatures of internal rotation discovered in the Kepler data of five slowly pulsating B stars.
