Proper motions of field L and T dwarfs -II
S. L. Casewell, R. F. Jameson, M. R. Burleigh
By using images taken with WFCAM on UKIRT and SofI on the NTT and combining them with 2MASS we have measured proper motions for 126 L and T dwarfs in the dwarf archive. Two of thes…
Proper motions of field L and T dwarfs
R. F. Jameson, S. L. Casewell, N. P. Bannister +4
The proper motion measurements for 143 previously known L and T dwarfs are presented. From this sample we identify and discuss 8 high velocity L dwarfs. We also find 4 new wide com…
L and T dwarfs in the Hyades and Ursa Major moving groups
N. P. Bannister, R. F. Jameson
We have used the moving cluster method to identify three L dwarfs and one T dwarf in the Ursa Major/Sirius moving group (age 400 Myr). Five L dwarfs and two T dwarfs are found to b…
Heavy element abundance patterns in hot DA white dwarfs
M. A. Barstow, S. A. good, J. B. Holberg +5
We present a series of systematic abundance measurements for 25 hot DA white dwarfs in the temperature range ~20000-110000K, based on far-UV spectroscopy with STIS/GHRS on HST, IUE…
