Parallaxes of five L Dwarfs with a Robotic Telescope
Y. Wang, H. R. A. Jones, R. L. Smart +14
We report the parallax and proper motion of five L dwarfs obtained with observations from the robotic Liverpool Telescope. Our derived proper motions are consistent with published…
A spectroscopic and proper motion search of Sloan digital Sky Survey: red subdwarfs in binary systems
Z. H. Zhang, D. J. Pinfield, B. Burningham +13
Red subdwarfs in binary systems are crucial for both model calibration and spectral classification. We search for red subdwarfs in binary systems from a sample of high proper motio…
Seventy six T dwarfs from the UKIDSS LAS: benchmarks, kinematics and an updated space density
Ben Burningham, C. V. Cardoso, L. Smith +34
We report the discovery of 76 new T dwarfs from the UKIDSS Large Area Survey (LAS). Near-infrared broad and narrow-band photometry and spectroscopy are presented for the new object…
Discovery of the benchmark metal poor T8 dwarf BD+01 2920B
D. J. Pinfield, B. Burningham, N. Lodieu +20
We have searched the WISE first data release for widely separated (<10,000AU) late T dwarf companions to Hipparcos and Gliese stars. We have discovered a new binary system containi…
The properties of the T8.5p dwarf Ross 458C
Ben Burningham, S. K. Leggett, D. Homeier +12
We present near-infrared photometry and spectroscopy, and warm-Spitzer IRAC photometry of the young very cool T dwarf Ross 458C, which we have typed as T8.5p. By applying the fiduc…
The discovery of the T8.5 dwarf UGPS J0521+3640
Ben Burningham, P. W. Lucas, S. K. Leggett +15
We have carried out a search for late-type T dwarfs in the UKIDSS Galactic Plane Survey 6th Data Release. The search yielded two persuasive candidates, both of which have been conf…
