Keck Laser Guide Star Adaptive Optics Monitoring of the M8+L7 Binary LHS 2397aAB: First Dynamical Mass Benchmark at the L/T Transition
Trent J. Dupuy, Michael C. Liu, Michael J. Ireland
We present Keck LGS AO imaging and aperture masking observations of the M8+L7 binary LHS 2397aAB. Together with archival HST, Gemini-North, and VLT data, our observations span 11.8…
Fundamental Properties of Low-Mass Stars and Brown Dwarfs
Michael C. Liu, Keivan G. Stassun, France Allard +7
Precise measurements of the fundamental properties of low-mass stars and brown dwarfs are key to understanding the physics underlying their formation and evolution. While there has…
Keck Laser Guide Star Adaptive Optics Monitoring of 2MASS J1534-2952AB: First Dynamical Mass Determination of a Binary T Dwarf
Michael C. Liu, Trent J. Dupuy, Michael J. Ireland
(Abridged) We present multi-epoch imaging of the T5.0+T5.5 binary 2MASS J1534-2952AB obtained with the Keck laser guide star adaptive optics system. Combined with an extensive (re-…
Subtle Signatures of Multiplicity in Late-type Dwarf Spectra: The Unresolved M8.5 + T5 Binary 2MASS J03202839-0446358
Adam J. Burgasser, Michael C. Liu, Michael J. Ireland +2
Evidence is presented that 2MASS J03202839-0446358, a late-type dwarf with discrepant optical (M8:) and near-infrared (L1) spectral types, is an as-yet unresolved stellar/brown dwa…
CFBDS J005910.90-011401.3: reaching the T-Y Brown Dwarf transition?
Philippe Delorme, Xavier Delfosse, Loic Albert +9
We report the discovery of CFBDS J005910.90-011401.3 (hereafter CFBDS0059), the coolest brown dwarf identified to date. We found CFBDS0059 using i' and z' images from the Canada-Fr…
Cluster Mass Functions in the Large and Small Magellanic Clouds: Fading and Size of Sample Effects
D. A. Hunter, B. G. Elmegreen, T. J. Dupuy +1
The properties of 939 star clusters in the Large and Small Magellanic Clouds were determined from ground-based CCD images in UBVR passbands. The areal coverage was extensive, corre…
