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…
Detection and Bulk Properties of the HR 8799 Planets with High Resolution Spectroscopy
Jason J. Wang, Jean-Baptiste Ruffio, Evan Morris +49
Using the Keck Planet Imager and Characterizer (KPIC), we obtained high-resolution (R35,000) -band spectra of the four planets orbiting HR 8799. We clearly detected \water…
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…
Large Adaptive Optics Survey for Substellar Objects (LASSO) Around Young, Nearby, Low-mass Stars with Robo-AO
Maissa Salama, James Ou, Christoph Baranec +16
We present results from the Large Adaptive optics Survey for Substellar Objects (LASSO), where the goal is to directly image new substellar companions (<70 M) at wide orbit…
A Novel Survey for Young Substellar Objects with the W-band filter III: Searching for very low mass brown dwarfs in Serpens South and Serpens Core
Sophie Dubber, Beth Biller, Katelyn Allers +10
We present CFHT photometry and IRTF spectroscopy of low-mass candidate members of Serpens South and Serpens Core (430 pc, 0.5 Myr), identified using a novel combination…
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.…
