High proper motion objects from the UKIDSS Galactic plane survey
(2014-09-21)
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a seven year effort to survey ~1800 deg2 of the northern Galactic plane in the J, H, and K passbands. The survey included a second epoch of K-band data, with a baseline ...
The discovery of a T6.5 subdwarf
(2014-05)
We report the discovery of ULAS J131610.28+075553.0, an sdT6.5 dwarf in the UKIDSS Large Area Survey 2 epoch proper motion catalogue. This object displays significant spectral peculiarity, with the largest yet seen deviations ...
The extremely red L dwarf ULAS J222711-004547-dominated by dust
(2014-03)
We report the discovery of a peculiar L dwarf from the United Kingdom Infrared Deep Sky Survey Large Area Survey, ULAS J222711-004547. The very red infrared photometry (MKO J-K = 2.79 +/- 0.06, WISEW1-W2 = 0.65 +/- 0.05) ...
A 1500 deg(2) near infrared proper motion catalogue from the UKIDSS Large Area Survey
(2014-02)
The United Kingdom Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) began in 2005, with the start of the UKIDSS programme as a 7 year effort to survey roughly 4000 deg(2) at high Galactic latitudes in Y, J, H and ...
NPARSEC : NTT Parallaxes of Southern Extremely Cool objects. Goals, targets, procedures and first results
(2013-08)
The discovery and subsequent detailed study of T dwarfs have provided many surprises and pushed the physics and modelling of cool atmospheres in unpredicted directions. Distance is a critical parameter for studies of these ...
76 T dwarfs from the UKIDSS LAS : benchmarks, kinematics and an updated space density
(2013-07)
We report the discovery of 76 new T dwarfs from the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS). Near-infrared broad- and narrow-band photometry and spectroscopy are presented for the new objects, along ...
