ABSTRACT: We have used blue near-infrared colours to select a group of 12 spectroscopically-confirmed UKIDSS T dwarfs later than T4. From amongst these we identify the first two kinematic halo T-dwarf candidates.
Blue near-infrared colours have been attributed to collisionally-induced hydrogen absorption, which is enhanced by either high surface gravity or low metallicity.
Proper motions are measured and distances estimated, allowing the determination of tangential velocities.
U and V components are estimated for our objects by assuming Vrad=0. From this, ULAS J0926+0835 is found to have U=62 kms-1 and V=-140 kms-1 and ULAS J1319+1209 is found to have U=192 kms-1 and V=-92 kms-1.
These values are consistent with potential halo membership. However, these are not the bluest objects in our selection. The bluest is ULAS J1233+1219, with J-K=-1.16 ± 0.07, and surprisingly this object is found to have young disc-like U and V.
Our sample also contains Hip 73786B, companion to the metal-poor K5 dwarf Hip 73786.
Hip 73786 is a metal-poor star, with [Fe/H]=-0.3 ± 0.1 and is located at a distance of 19 ± 0.7 pc. U, V, W space velocity
components are calculated for Hip 73786A and B, finding that U=-48 ± 7 kms-1, V=-75 ± 4 kms-1 and W=-44 ± 8 kms-1. From the properties of the primary, Hip 73786B is found to be at least 1.6 Gyr old.
As a metal poor object, Hip 73786B represents an important addition to the sample of known T dwarf benchmarks.
