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 cool brown dwarf Gliese 229 B is a close binary
Jerry W. Xuan, A. Mérand, W. Thompson +76
Owing to their similarities with giant exoplanets, brown dwarf companions of stars provide insights into the fundamental processes of planet formation and evolution. From their orb…
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…
JWST/NIRCam 4-5 m Imaging of the Giant Planet AF Lep b
Kyle Franson, William O. Balmer, Brendan P. Bowler +23
With a dynamical mass of , the recently discovered giant planet AF Lep b is the lowest-mass imaged planet with a direct mass measurement. Its youth and spectra…
Keck Primary Mirror Closed-Loop Segment Control using a Vector-Zernike Wavefront Sensor
Maissa Salama, Charlotte Guthery, Vincent Chambouleyron +17
We present the first on-sky segmented primary mirror closed-loop piston control using a Zernike wavefront sensor (ZWFS) installed on the Keck II telescope. Segment co-phasing error…
Direct-imaging Discovery of a Substellar Companion Orbiting the Accelerating Variable Star, HIP 39017
Taylor L. Tobin, Thayne Currie, Yiting Li +23
We present the direct-imaging discovery of a substellar companion (a massive planet or low-mass brown dwarf) to the young, Doradus-type variable star, HIP 39017 (HD 65526). The…
