Identifying nearby field T dwarfs in the UKIDSS Galactic Clusters Survey
N. Lodieu, B. Burningham, N. C. Hambly +1
We present the discovery of two new late-T dwarfs identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) Data Release 2 (DR2). These T dwarfs are…
Dynamical masses for the nearest brown dwarf binary: Epsilon Indi Ba, Bb
C. V. Cardoso, M. J. McCaughrean, R. R. King +6
We present preliminary astrometric results for the closest known brown dwarf binary to the Sun: Epsilon Indi Ba, Bb at a distance of 3.626 pc. Via ongoing monitoring of the relativ…
Epsilon Indi Ba, Bb: a spectroscopic study of the nearest known brown dwarfs
Robert R. King, Mark J. McCaughrean, Derek Homeier +3
The discovery of Epsilon Indi Ba and Bb, a nearby binary brown dwarf system with a main-sequence companion, allows a concerted campaign to characterise the physical parameters of t…
Cool White Dwarfs Identified in the Second Data Release of the UKIRT Infrared Deep Sky Survey
N. Lodieu, S. K. Leggett, P. Bergeron +1
We have paired the Second Data Release of the Large Area Survey of the UKIRT Infrared Deep Sky Survey with the Fifth Data Release of the Sloan Digital Sky Survey to identify ten co…
Ultracool Subdwarfs: The Halo Population Down to the Substellar Limit
Adam J. Burgasser, Sebastien Lepine, Nicolas Lodieu +5
Ultracool subdwarfs are low luminosity, late-type M and L dwarfs that exhibit spectroscopic indications of subsolar metallicity and halo kinematics. Their recent discovery and ongo…
Fifteen new T dwarfs discovered in the UKIDSS Large Area Survey
D. J. Pinfield, B. Burningham, M. Tamura +32
We present the discovery of fifteen new T2.5-T7.5 dwarfs (with estimated distances between ~24-93pc, identified in the first three main data releases of the UKIRT Infrared Deep Sky…
