A Volume-Limited Sample of Ultracool Dwarfs. I. Construction, Space Density, and a Gap in the L/T Transition
William M. J. Best, Michael C. Liu, Eugene A. Magnier +1
We present a new volume-limited sample of L0-T8 dwarfs out to 25 pc defined entirely by parallaxes, using our recent measurements from UKIRT/WFCAM along with Gaia DR2 and literatur…
Direct radio discovery of a cold brown dwarf
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +9
Magnetospheric processes seen in gas-giants such as aurorae and circularly-polarized cyclotron maser radio emission have been detected from some brown dwarfs. However, previous rad…
Uniform Forward-Modeling Analysis of Ultracool Dwarfs. I. Methodology and Benchmarking
Zhoujian Zhang, Michael C. Liu, Mark S. Marley +2
We present a forward-modeling framework using the Bayesian inference tool Starfish and cloudless Sonora-Bobcat model atmospheres to analyze low-resolution () near-i…
The Hawaii Infrared Parallax Program. IV. A Comprehensive Parallax Survey of L0-T8 dwarfs with UKIRT
William M. J. Best, Michael C. Liu, Eugene A. Magnier +1
We present parallaxes, proper motions, and -band photometry for 348 L and T dwarfs measured using the wide-field near-infrared camera WFCAM on the United Kingdom Infrared Telesc…
Spitzer Variability Properties of Low-Gravity L Dwarfs
Johanna M. Vos, Beth A. Biller, Katelyn N. Allers +17
We present \textit{Spitzer Space Telescope} variability monitoring observations of three low-gravity L dwarfs with previous detections of variability in the near-IR, 2MASS J0045+16…
The Parallax of VHS J1256-1257 from CFHT and Pan-STARRS 1
Trent J. Dupuy, Michael C. Liu, Eugene A. Magnier +6
We present new parallax measurements from the CFHT Infrared Parallax Program and the Pan-STARRS 3 Steradian Survey for the young ( Myr) triple system VHS J125601…
