Hubble Space Telescope NICMOS Observations of T Dwarfs: Brown Dwarf Multiplicity and New Probes of the L/T Transition
Adam J. Burgasser, J. Davy Kirkpatrick, Kelle L. Cruz +5
We present the results of a Hubble Space Telescope NICMOS imaging survey of 22 T-type field brown dwarfs. Five are resolved as binary systems with angular separations of 0"05-0"35,…
Binarity in Brown Dwarfs: T Dwarf Binaries Discovered with the Hubble Space Telescope WPFC2
Adam J. Burgasser, J. Davy Kirkpatrick, I. Neill Reid +3
(abridged) We present the discovery of two T dwarf binaries, 2MASS 1225-2739AB and 2MASS 1534-2952AB, identified in a sample of ten T dwarfs imaged with the Hubble Space Telescope…
The Spectra of T Dwarfs I: Near-Infrared Data and Spectral Classification
Adam J. Burgasser, J. Davy Kirkpatrick, Michael E. Brown +9
We present near-infrared spectra for a sample of T dwarfs, including eleven new discoveries made using the Two Micron All Sky Survey. These objects are distinguished from warmer (L…
Discovery of a Bright Field Methane (T-type) Brown Dwarf by 2MASS
Adam J. Burgasser, John C. Wilson, J. Davy Kirkpatrick +8
We report the discovery of a bright (J = 13.830.03) methane brown dwarf, or T dwarf, by the Two Micron All Sky Survey. This object, 2MASSI J0559191-140448, is the first brown…
Detection of H Alpha Emission in a Methane (T-Type) Brown Dwarf
Adam J. Burgasser, J. Davy Kirkpatrick, I. Neill Reid +3
We report the detection of H{} emission in the T dwarf (methane brown dwarf) 2MASSW J1237392+652615 over three days using the Keck Low Resolution Imaging Spectrograph. The measu…
Discovery of a Brown Dwarf Companion to Gliese 570ABC: A 2MASS T Dwarf Significantly Cooler than Gliese 229B
A. J. Burgasser, J. D. Kirkpatrick, R. M. Cutri +10
We report the discovery of a widely separated (258$\farcs3\pm0\farcs$4) T dwarf companion to the Gl 570ABC system. This new component, Gl 570D, was initially identified from the Tw…
