Using Narrow Band Photometry to Classify Stars and Brown Dwarfs
A. K. Mainzer, Ian S. McLean, J. L. Sievers +1
We present a new system of narrow band filters in the near infrared that can be used to classify stars and brown dwarfs. This set of four filters, spanning the H band, can be used…
Identifying Young Brown Dwarfs Using Gravity-Sensitive Spectral Features
Mark R. McGovern, J. Davy Kirkpatrick, Ian S. McLean +3
We report the initial results of the Brown Dwarf Spectroscopic Survey Gravity Project, to study gravity sensitive features as indicators of youth in brown dwarfs. Low-resolution (R…
High Precision Stellar Radial Velocities in the Galactic Center
Donald F. Figer
We present radial velocities for 85 cool stars projected onto the central parsec of the Galaxy. The majority of these velocities have relative errors of 1 km/s, or a factor o…
Using Narrow Band Photometry to Detect Young Brown Dwarfs in IC348
A. K. Mainzer, Ian S. McLean
We report the discovery of a population of young brown dwarf candidates in the open star cluster IC348 and the development of a new spectroscopic classification technique using nar…
The First Substellar Subdwarf? Discovery of a Metal-poor L Dwarf with Halo Kinematics
Adam J. Burgasser, J. Davy Kirkpatrick, Adam Burrows +6
We present the discovery of the first L-type subdwarf, 2MASS J05325346+8246465. This object exhibits enhanced collision-induced H absorption, resulting in blue NIR colors ($J-K…
The First Measurement of Spectral Lines in a Short-Period Star Bound to the Galaxy's Central Black Hole: A Paradox of Youth
A. M. Ghez, G. Duchene, K. Matthews +11
We have obtained the first detection of spectral absorption lines in one of the high-velocity stars in the vicinity of the Galaxy's central supermassive black hole. Both Brgamma (2…
