Identification of a Wide, Low-Mass Multiple System Containing the Brown Dwarf 2MASS J0850359+105716
Jacqueline K. Faherty, Adam J. Burgasser, John J. Bochanski +3
We report our discovery of NLTT 20346 as an M5+M6 companion system to the tight binary (or triple) L dwarf 2MASS J0850359+105716. This nearby (~31 pc), widely separated (~7700 AU)…
The Sloan Digital Sky Survey Data Release 7 M Dwarf Spectroscopic Catalog
Andrew A. West, Dylan P. Morgan, John J. Bochanski +17
We present a spectroscopic catalog of 70,841 visually inspected M dwarfs from the seventh data release (DR7) of the Sloan Digital Sky Survey (SDSS). For each spectrum, we provide m…
Statistical Parallax Analysis of SDSS M Dwarfs
Suzanne L. Hawley, John J. Bochanski, Andrew A. West
We report on the analysis of ~22,000 M dwarfs using a statistical parallax method. This technique employs a maximum-likelihood formulation to simultaneously solve for the absolute…
Low-Mass Stars in the Sloan Digital Sky Survey: Galactic Structure, Kinematics, and the Luminosity Function
John J. Bochanski
Modern sky surveys, such as the Sloan Digital Sky Survey and the Two-Micron All Sky Survey, have revolutionized the study of low-mass stars. With millions of photometric and spectr…
Cool Star Science with the FIRE Spectrograph
Adam J. Burgasser, Robert A. Simcoe, John J. Bochanski +7
The Folded-port InfraRed Echellette (FIRE) has recently been commissioned on the Magellan 6.5m Baade Telescope. This single object, near-infrared spectrometer simultaneously covers…
MARVELS-1b: A Short-Period, Brown Dwarf Desert Candidate from the SDSS-III MARVELS Planet Search
Brian L. Lee, Jian Ge, Scott W. Fleming +59
We present a new short-period brown dwarf candidate around the star TYC 1240-00945-1. This candidate was discovered in the first year of the Multi-object APO Radial Velocity Exopla…
