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…
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…
L dwarfs in the Hyades
E. Hogan, R. F. Jameson, S. L. Casewell +2
We present the results of a proper motion survey of the Hyades to search for brown dwarfs, based on UKIDSS and 2MASS data. This survey covers ~275 square degrees to depth of K~15 m…
The ages of L dwarfs
R. F. Jameson, N. Lodieu, S. L. Casewell +2
We present a new method to derive the age of young (<0.7 Gyr) L dwarfs based on their near-infrared photometry, colours, and distances. The method is based on samples of L dwarfs b…
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…
GRB 060206 and the quandary of achromatic breaks in afterglow light curves
P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers +20
Gamma-ray burst afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX era. We present our multi-wavelength analysis of GRB…
