Exploring the substellar temperature regime down to ~550K
Ben Burningham, D. J. Pinfield, S. K. Leggett +15
We report the discovery of three very late T dwarfs in the UKIRT Infrared Deep Sky Survey (UKIDSS) Third Data Release: ULAS J101721.40+011817.9 (ULAS1017), ULAS J123828.51+095351.3…
HN Peg B: A Test of Models of the L to T Dwarf Transition
S. K. Leggett, D. Saumon, Loic Albert +7
Luhman and collaborators recently discovered an early-T dwarf companion to the G0 dwarf star HN Peg, using Spitzer Infrared Array Camera (IRAC) images. Companionship was establishe…
Eight new T4.5-T7.5 dwarfs discovered in the UKIDSS Large Area Survey Data Release 1
N. Lodieu, D. J. Pinfield, S. K. Leggett +4
We present eight new T4.5-T7.5 dwarfs identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) Data Release 1 (DR1). In addition we have recovered the T4.5…
Physical parameters of two very cool T dwarfs
D. Saumon, M. S. Marley, S. K. Leggett +8
We present new infrared spectra of the T8 brown dwarf 2MASS J04151954-0935066: 2.9-4.1 micron spectra obtained with the Infrared Camera and Spectrograph on the Subaru Telescope, an…
New members in the Upper Sco association from the UKIDSS Early Data Release
N. Lodieu, N. C. Hambly, R. F. Jameson
We present the results of a 9.3 square degree infrared (ZYJHK) survey in the Upper Scorpius association extracted from the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Cluster…
Ammonia as a tracer of chemical equilibrium in the T7.5 dwarf Gliese 570D
D. Saumon, M. S. Marley, M. C. Cushing +4
We present the first analysis of an optical to mid-infrared spectrum of the T7.5 dwarf Gliese 570D with model atmospheres, synthetic spectra, and brown dwarf evolution sequences. W…
