The first planet detected in the WTS : an inflated hot-Jupiter in a 3.35 day orbit around a late F-star [ERRATUM]
(2014-11-11)
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 August 2007. Light curves comprising ...
A deep WISE search for very late type objects and the discovery of two halo/thick-disc T dwarfs : WISE 0013+0634 and WISE 0833+0052
(2014-01-11)
A method is defined for identifying late-T and Y dwarfs in WISE down to low values of signal-to-noise. This requires a WISE detection only in the W2-band and uses the statistical properties of the WISE multiframe measurements ...
A spectroscopic and proper motion search of Sloan Digital Sky Survey : red subdwarfs in binary systems
(2013-09)
Red subdwarfs in binary systems are crucial for both model calibration and spectral classification. We search for red subdwarfs in binary systems from a sample of high proper motion objects with Sloan Digital Sky Survey ...
Benchmark low-mass objects in Moving Groups
(EDP Sciences, 2013)
In order to compile a sample of ultracool dwarfs that will serve as benchmarks for testing theoretical formation and evolutionary models, we selected low-mass cool (>M7) objects that are potentially members of five known ...
Purple dwarfs : New L subdwarfs from UKIDSS and SDSS
(EDP Sciences, 2013)
The first L subdwarf was a discovered only ten years ago. Less than ten L subdwarfs been published in the literature to date. Metal-poor ultracool atmospheres has not been well understood. Halo mass function cross substellar ...
Identifying ultra-cool dwarfs at low Galactic latitudes : a southern candidate catalogue
(2012-12)
We present an ultra-cool dwarf (UCD) catalogue compiled from low southern Galactic latitudes and mid-plane, from a cross-correlation of the Two Micron All-Sky Survey (2MASS) and the SuperCOSMOS survey. The catalogue contains ...
Low-mass Objects in Moving Groups
(Astronomical Society of the Pacific, 2010)
We present here the kinematic study of part of a 132 target sample of low-mass objects, previously selected by photometric and astrometric criteria as possible members to five young moving groups (MGs): Local Association ...
Spectroscopy and kinematics of low-mass members of young moving groups
(2010)
We study a target sample of 68 low-mass objects (with spectral types in the range M4.5–L1) previously selected via photometric and astrometric criteria, as possible members of five young moving groups: the Local Association ...
