High-precision photometry by telescope defocussing. VII. The ultra-short period planet WASP-103
John Southworth, L. Mancini, S. Ciceri +25
We present 17 transit light curves of the ultra-short period planetary system WASP-103, a strong candidate for the detection of tidally-induced orbital decay. We use these to estab…
Searching for variable stars in the cores of five metal rich globular clusters using EMCCD observations
Jesper Skottfelt, D. M. Bramich, R. Figuera Jaimes +31
In this paper, we present the analysis of time-series observations from 2013 and 2014 of five metal rich ([Fe/H] -1) globular clusters: NGC~6388, NGC~6441, NGC~6528, NGC~6638,…
Kepler-432 b: a massive planet in a highly eccentric orbit transiting a red giant
Simona Ciceri, Jorge Lillo-Box, John Southworth +3
We report the first disclosure of the planetary nature of Kepler-432 b (aka Kepler object of interest KOI-1299.01). We accurately constrained its mass and eccentricity by high-prec…
HATS-6b: A Warm Saturn Transiting an Early M Dwarf Star, and a Set of Empirical Relations for Characterizing K and M Dwarf Planet Hosts
J. D. Hartman, D. Bayliss, R. Brahm +25
We report the discovery by the HATSouth survey of HATS-6b, an extrasolar planet transiting a V=15.2 mag, i=13.7 mag M1V star with a mass of 0.57 Msun and a radius of 0.57 Rsun. HAT…
Radial velocity confirmation of Kepler-91 b. Additional evidence of its planetary nature using the Calar Alto/CAFE instrument
J. Lillo-Box, D. Barrado, Th. Henning +6
The object transiting the star Kepler-91 was recently assessed as being of planetary nature. The confirmation was achieved by analysing the light-curve modulations observed in the…
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…
