Young L Dwarfs Identified in the Field: A Preliminary Low-Gravity, Optical Spectral Sequence from L0 to L5
Kelle L. Cruz, J. Davy Kirkpatrick, Adam J. Burgasser
We present an analysis of 23 L dwarfs whose optical spectra display unusual features. Twenty-one were uncovered during our search for nearby, late-type objects using the Two Micron…
Meeting the Cool Neighbors X: Ultracool dwarfs from the 2MASS All-Sky Data Release
I. Neill Reid, Kelle L. Cruz, J. Davy Kirkpatrick +5
Using data from the 2MASS All-Sky Point Source Catalogue, we have extended our census of nearby ultracool dwarfs to cover the full celestial sphere above Galactic latitute 15 degre…
Follow-up observations of binary ultra-cool dwarfs
H. Bouy, E. L. Martin, W. Brandner +12
Astrometric observations of resolved binaries provide estimates of orbital periods and will eventually lead to measurement of dynamical masses. Only a few very low mass star and br…
Meeting the Cool Neighbors. IX. The Luminosity Function of M7-L8 Ultracool Dwarfs in the Field
Kelle L. Cruz, I. Neill Reid, J. Davy Kirkpatrick +7
We present a 20-pc, volume-limited sample of M7-L8 dwarfs created through spectroscopic follow-up of sources selected from the Two Micron All Sky Survey (2MASS) Second Incremental…
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,…
The 2MASS Wide-Field T Dwarf Search. III. Seven New T Dwarfs and Other Cool Dwarf Discoveries
Adam J. Burgasser, Michael W. McElwain, J. Davy Kirkpatrick +3
We present the discovery of seven new T dwarfs identified in the Two Micron All Sky Survey. Low-resolution (R150) 0.8--2.5 micron spectroscopy obtained with the IRTF SpeX ins…
