The UKIRT Infrared Deep Sky Survey (UKIDSS)
The final version published in MNRAS August 2007 included significant revisions including significant revisions to the original version April 2006.
Discovery of a young planetary mass companion to the nearby M dwarf VHS J125601.92-125723.9
In a search for common proper motion companions using the VISTA Hemisphere Survey and 2MASS catalogs we have identified a very red (J-Ks=2.47 mag) late-L dwarf companion of a previously unrecognized
Epsilon Indi B: a new benchmark T dwarf
We have identified a new early T dwarf only 3.6pc from the Sun, as a common proper motion companion (separation 1459AU) to the K5V star Epsilon Indi (HD209100). As such, Epsilon Indi B is one of the
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey – I. The Pleiades★
Over the past decades open clusters have been the subject of many studies. Such studies are crucial considering that the universality of the initial mass function is still a subject of current
A very cool brown dwarf in UKIDSS DR1
We report the discovery of a very cool brown dwarf, ULAS J003402.77−005206.7 (ULAS J0034−00), identified in the UKIRT Infrared Deep Sky Survey First Data Release. We provide optical, near-infrared,
New brown dwarfs in Upper Sco using UKIDSS Galactic Cluster Survey science verification data
We present rst results from a deep (J = 18.7), wide-eld (6.5 square degrees) infrared (ZY JHK) survey in the Upper Sco association conducted within the science verication phase of the UKIRT Infrared
Multi-fibre optical spectroscopy of low-mass stars and brown dwarfs in Upper Scorpius ,,
Context. Knowledge of the mass function in open clusters constitutes one way to critically examine the formation mechanisms proposed to explain the existence of low-mass stars and brown dwarfs. Aims.
WTS-2 b: a hot Jupiter orbiting near its tidal destruction radius around a K dwarf
We report the discovery of WTS-2 b, an unusually close-in 1.02-d hot Jupiter (M-P = 1.12M(J), R-P = 1.30R(J)) orbiting a K2V star, which has a possible gravitationally bound M-dwarf companion at 0.6
SSSPM J1102-3431: A probable new young brown dwarf member of the TW Hydrae Association
We have used archival survey data, most importantly from the SuperCOSMOS Sky Surveys, to derive accurate proper motions and thus confirm the membership of two previously announced isolated brown
A census of very-low-mass stars and brown dwarfs in the sigma Orionis cluster
Context. The knowledge of the initial mass function (IMF) in open clusters constitutes one way of constraining the formation of low-mass stars and brown dwarfs, along with the frequency of multiple
