BDKP. V. Radial & rot. velocities of M, L, T dwarfs
We report multiepoch radial velocities, rotational velocities, and atmospheric parameters for 37 T-type brown dwarfs observed with Keck/NIRSPEC. Using a Markov Chain Monte Carlo... -
Parallaxes of late-T and Y dwarfs
We present preliminary trigonometric parallaxes of 184 late-T and Y dwarfs using observations from Spitzer (143), the U.S. Naval Observatory (18), the New Technology Telescope... -
NIR spectra of 2 extreme T-type subdwarfs
We present the discoveries of WISEAJ041451.67-585456.7 and WISEAJ181006.18-101000.5, two low-temperature (1200-1400K), high proper motion T-type subdwarfs. Both objects were... -
COCONUTS. I. Spectra of a WD and T4 comoving syst.
We present the first discovery from the COol Companions ON Ultrawide orbiTS (COCONUTS) program, a large-scale survey for wide-orbit planetary and substellar companions. We have... -
Brown dwarf surface gravities with Keck/NIRSPEC
We combine 131 new medium-resolution (R~2000) J-band spectra of M, L, and T dwarfs from the Keck NIRSPEC Brown Dwarf Spectroscopic Survey (BDSS) with 97 previously published... -
NIR light curve of 2MASS J00501994-3322402
Only a handful of late T brown dwarfs have been monitored for spectrophotometric variability, leaving incomplete the study of the atmospheric cloud structures of the coldest... -
The Perkins INfrared Exosatellite Survey. I.
We describe the Perkins INfrared Exosatellite Survey (PINES), a near-infrared photometric search for short-period transiting planets and moons around a sample of 393... -
RVs of the late-T dwarf GL 758 B host star
Gl 758 B is a late-T dwarf orbiting a metal-rich Sun-like star at a projected separation of {rho}~1.6" (25 au). We present four epochs of astrometry of this system with NIRC2 at...
