L' AND M' Photometry Of Ultracool Dwarfs
- D. Golimowski, S. Leggett, +16 authors J. Brinkmann
- Physics
- 19 February 2004
We have compiled L' (3.4?4.1 ?m) and M' (4.6?4.8 ?m) photometry of 63 single and binary M, L, and T dwarfs obtained at the United Kingdom Infrared Telescope using the Mauna Kea Observatory filter… Expand
Near - infrared photometry and spectroscopy of L and T dwarfs: The Effects of temperature, clouds, and gravity
- G. Knapp, S. Leggett, +4 authors E. al.
- Physics
- 19 February 2004
We present new JHK photometry on the MKO-NIR system and JHK spectroscopy for a large sample of L and T dwarfs. Photometry has been obtained for 71 dwarfs, and spectroscopy for 56. The sample… Expand
Characterization of M, L, and T Dwarfs in the Sloan Digital Sky Survey
- S. Hawley, K. Covey, +5 authors Institute for Advanced Study
- Physics
- 3 April 2002
An extensive sample of M, L, and T dwarfs identified in the Sloan Digital Sky Survey (SDSS) has been compiled. The sample of 718 dwarfs includes 677 new objects (629 M dwarfs and 48 L dwarfs),… Expand
Toward Spectral Classification of L and T Dwarfs: Infrared and Optical Spectroscopy and Analysis
- T. Geballe, G. Knapp, S. Leggett, X. Fan, D. Golimowski, E. al.
- Physics
- 28 August 2001
We present 0.6-2.5 μm, R 400 spectra of 27 cool, low-luminosity stars and substellar objects. Based on these and previously published spectra, we develop a preliminary spectral classification system… Expand
A Unified Near-Infrared Spectral Classification Scheme for T Dwarfs
- A. Burgasser, T. Geballe, S. Leggett, J. Kirkpatrick, D. Golimowski
- Physics
- 4 October 2005
A revised near-infrared classification scheme for T dwarfs is presented, based on and superseding prior schemes developed by Burgasser and coworkers and Geballe and coworkers, and defined following… Expand
Preliminary Parallaxes of 40 L and T Dwarfs from the US Naval Observatory Infrared Astrometry Program
- F. Vrba, A. Henden, +12 authors J. Brinkman
- Physics
- 11 February 2004
We present preliminary trigonometric parallaxes and proper motions for 22 L dwarfs and 18 T dwarfs measured using the ASTROCAM infrared imager on the US Naval Observatory (USNO) 1.55 m Strand… Expand
The Luminosity and Mass Functions of Low-mass Stars in the Galactic Disk. II. The Field
