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…
The Formation and Architecture of Young Planetary Systems
Adam L. Kraus, Kevin Covey, Michael Liu +5
Newly-formed planetary systems with ages of <10 Myr offer many unique insights into the formation, evolution, and fundamental properties of extrasolar planets. These planets have f…
BD-22 5866: A Low-mass Quadruple-lined Spectroscopic AND Eclipsing Binary
Evgenya Shkolnik, Michael C. Liu, I. Neill Reid +4
We report our discovery of an extremely rare, low mass, quadruple-lined spectroscopic binary BD-22 5866 (=NLTT 53279, integrated spectral type = M0 V), found during an ongoing sear…
Physical and Spectral Characteristics of the T8 and Later-Type Dwarfs
S. K. Leggett, M. S. Marley, R. Freedman +5
We use new and published near-IR spectra, with synthetic spectra, to derive physical properties of three of the latest-type T dwarfs. A new R~1700 spectrum of the T7.5 dwarf HD 365…
Initial mass function effects on the colour evolution of disk galaxies
P. Westera, M. Samland, S. J. Kautsch +2
In this work, we want to find out if the IMF can be determined from colour images, integrated colours, or mass-to-light ratios, especially at high redshift, where galaxies cannot b…
Discovery of a High Proper Motion L Dwarf Binary: 2MASS J15200224-4422419AB
Adam J. Burgasser, Dagny L. Looper, J. Davy Kirkpatrick +1
We report the discovery of the wide L1.5+L4.5 binary 2MASS J15200224-4422419AB, identified during spectroscopic followup of high proper motion sources selected from the Two Micron…
