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…
Warm Ice Giant GJ 3470b. II Revised Planetary and Stellar Parameters from Optical to Near-infrared Transit Photometry
Lauren I. Biddle, Kyle A. Pearson, Ian J. M. Crossfield +19
It is important to explore the diversity of characteristics of low-mass, low-density planets to understand the nature and evolution of this class of planets. We present a homogeneo…
Physical properties of the WASP-67 planetary system from multi-colour photometry
L. Mancini, J. Southworth, S. Ciceri +29
The extrasolar planet WASP-67 b is the first hot Jupiter definitively known to undergo only partial eclipses. The lack of the second and third contact point in this planetary syste…
Physical properties, starspot activity, orbital obliquity, and transmission spectrum of the Qatar-2 planetary system from multi-colour photometry
L. Mancini, J. Southworth, S. Ciceri +6
We present seventeen high-precision light curves of five transits of the planet Qatar-2b, obtained from four defocussed 2m-class telescopes. Three of the transits were observed sim…
HATS-4b: A Dense Hot-Jupiter Transiting a Super Metal-Rich G Star
A. Jordán, R. Brahm, G. Á. Bakos +31
We report the discovery by the HATSouth survey of HATS-4b, an extrasolar planet transiting a V=13.46 mag G star. HATS-4b has a period of P = 2.5167 d, mass of Mp = 1.32 Mj, radius…
HATS-5b: A Transiting hot-Saturn from the HATSouth Survey
G. Zhou, D. Bayliss, K. Penev +26
We report the discovery of HATS-5b, a transiting hot-Saturn orbiting a G type star, by the HAT-South survey. HATS-5b has a mass of Mp=0.24 Mj, radius of Rp=0.91 Rj, and transits it…
