The Two-Colour EMCCD Instrument for the Danish 1.54m Telescope and SONG
Jesper Skottfelt, D. M. Bramich, M. Hundertmark +13
We report on the implemented design of a two-colour instrument based on electron multiplying CCD (EMCCD) detectors. This instrument is currently installed at the Danish 1.54m teles…
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,…
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…
A ring system detected around the Centaur (10199) Chariklo
F. Braga-Ribas, B. Sicardy, J. L. Ortiz +61
Until now, rings have been detected in the Solar System exclusively around the four giant planets. Here we report the discovery of the first minor-body ring system around the Centa…
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…
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…
