Improved Dynamical Masses for Six Brown Dwarf Companions Using Hipparcos and Gaia EDR3
G. Mirek Brandt, Trent J. Dupuy, Yiting Li +8
We present comprehensive orbital analyses and dynamical masses for the substellar companions Gl~229~B, Gl~758~B, HD~13724~B, HD~19467~B, HD~33632~Ab, and HD~72946~B. Our dynamical…
The Second Discovery from the COol Companions ON Ultrawide orbiTS (COCONUTS) Program: A Cold Wide-Orbit Exoplanet around a Young Field M Dwarf at 10.9 pc
Zhoujian Zhang, Michael C. Liu, Zachary R. Claytor +3
We present the identification of the COCONUTS-2 system, composed of the M3 dwarf L 34-26 and the T9 dwarf WISEPA J075108.79763449.6. Given their common proper motions and parall…
Uniform Forward-Modeling Analysis of Ultracool Dwarfs. II. Atmospheric Properties of 55 Late-T Dwarfs
Zhoujian Zhang, Michael C. Liu, Mark S. Marley +2
We present a large forward-modeling analysis for 55 late-T (T7-T9) dwarfs, using low-resolution () near-infrared spectra and cloudless Sonora-Bobcat model atmospheres.…
The Hawaii Infrared Parallax Program. V. New T-Dwarf Members and Candidate Members of Nearby Young Moving Groups
Zhoujian Zhang, Michael C. Liu, William M. J. Best +2
We present a search for new planetary-mass members of nearby young moving groups (YMGs) using astrometry for 694 T and Y dwarfs, including 447 objects with parallaxes, mostly produ…
