The first planet detected in the WTS: an inflated hot-Jupiter in a 3.35 day orbit around a late F-star [ERRATUM]
M. Cappetta, R. P. Saglia, J. L. Birkby +35
We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope (UKIRT) in…
WTS-2 b: a hot Jupiter orbiting near its tidal destruction radius around a K-dwarf
J. L. Birkby, M. Cappetta, P. Cruz +34
We report the discovery of WTS-2 b, an unusually close-in 1.02-day hot Jupiter (Mp=1.12MJ, Rp=1.363RJ) orbiting a K2V star, which has a possible gravitationally-bound M-dwarf compa…
Searching for transits in the WTS with difference imaging light curves
Jesus Zendejas, Johannes Koppenhoefer, Roberto P. Saglia +13
The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses ape…
A catalogue of bright (K < 9) M dwarfs
J. Frith, D. J. Pinfield, H. R. A. Jones +8
Using the Position and Proper Motion Extended-L (PPMXL) catalogue, we have used optical and near-infrared colour cuts together with a reduced proper motion cut to find bright M dwa…
A sensitivity analysis of the WFCAM Transit Survey for short-period giant planets around M dwarfs
Gábor Kovács, S. Hodgkin, B. Sipőcz +11
The WFCAM Transit Survey (WTS) is a near-infrared transit survey running on the United Kingdom Infrared Telescope (UKIRT), designed to discover planets around M dwarfs. The WTS act…
NLTT5306: The shortest Period Detached White Dwarf + Brown Dwarf Binary
P. R. Steele, R. P. Saglia, M. R. Burleigh +6
We have spectroscopically confirmed a brown dwarf mass companion to the hydrogen atmosphere white dwarf NLTT5306. The white dwarf's atmospheric parameters were measured using Sloan…
The first planet detected in the WTS: an inflated hot-Jupiter in a 3.35 day orbit around a late F-star
M. Cappetta, R. P. Saglia, J. L. Birkby +36
We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope. Light cur…
Discovery and characterisation of detached M-dwarf eclipsing binaries in the WFCAM Transit Survey
J. L. Birkby, S. V. Nefs, S. T. Hodgkin +17
We report the discovery of 16 detached M-dwarf eclipsing binaries with J<16 mag and provide a detailed characterisation of three of them, using high-precision infrared light curves…
Four ultra-short period eclipsing M-dwarf binaries in the WFCAM Transit Survey
S. V. Nefs, J. L. Birkby, I. A. G. Snellen +16
We report on the discovery of four ultra-short period (P<0.18 days) eclipsing M-dwarf binaries in the WFCAM Transit Survey. Their orbital periods are significantly shorter than of…
High resolution spectroscopy of the three dimensional cosmic web with close QSO groups
M. Cappetta, V. D'Odorico, S. Cristiani +2
We study the three-dimensional distribution of matter at z~2 using high resolution spectra of QSO pairs and simulated spectra drawn from cosmological hydro-dynamical simulations. W…
