Discovery of a Low-Mass Companion to the Accelerating Star HIP 53005 with Strongly Conflicting Mass Estimates

Taichi Uyama, Thayne Currie, Jerry W. Xuan +22

We present the discovery of a low-mass companion located at 0\farcs{}85 () from the early-type 1.2 Gyr-old star HIP 53005 using direct imagin…

SCExAO/CHARIS Spectroscopic Characterization of Cloudy L/T Transition Companion Brown Dwarf HIP 93398 B

Briley Lewis, Yiting Li, Aidan Gibbs +10

Brown dwarfs with measured dynamical masses and spectra from direct imaging are benchmarks that anchor substellar atmosphere cooling and evolution models. We present Subaru SCExAO/…

The Keck-HGCA Pilot Survey II: Direct Imaging Discovery of HD 63754 B, a ~20 au Massive Companion Near the Hydrogen Burning Limit

Yiting Li, Timothy D. Brandt, Kyle Franson +15

We present the joint astrometric and direct imaging discovery, mass measurement, and orbital analysis of HD 63754 B (HIP 38216 B), a companion near the stellar-substellar boundary…

Subaru/CHARIS High-Resolution Mode Spectroscopy of the Brown Dwarf Companion HD 33632 Ab

Aidan Gibbs, Briley Lewis, Michael Fitzgerald +6

Brown dwarfs (BD) are model degenerate in age and mass. High-contrast imaging and spectroscopy of BD companions to host stars where the mass and age can be independently constraine…

Dynamical and Atmospheric Characterization of the Substellar Companion HD 33632 Ab from Direct Imaging, Astrometry, and Radial-Velocity Data

Mona El Morsy, Thayne Currie, Danielle Bovie +17

We present follow-up SCExAO/CHARIS and -band (R 70) high-contrast integral field spectroscopy and Keck/NIRC2 photometry of directly-imaged brown dwarf companion HD 33…

JWST/NIRCam Detection of the Fomalhaut C Debris Disk in Scattered Light

Kellen Lawson, Joshua E. Schlieder, Jarron M. Leisenring +20

Observations of debris disks offer important insights into the formation and evolution of planetary systems. Though M dwarfs make up approximately 80% of nearby stars, very few M-d…
