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…
The Gliese 86 Binary System: A Warm Jupiter Formed in a Disk Truncated at 2 AU
Yunlin Zeng, Timothy D. Brandt, Gongjie Li +12
Gliese 86 is a nearby K dwarf hosting a giant planet on a 16-day orbit and an outer white dwarf companion on a century-long orbit. In this study we combine radial…
14 Her: a likely case of planet-planet scattering
Daniella C. Bardalez Gagliuffi, Jacqueline K. Faherty, Yiting Li +4
In this Letter, we measure the full orbital architecture of the two-planet system around the nearby K0 dwarf 14 Herculis. 14 Her (HD 145675, HIP 79248) is a middle-aged ($4.6^{+3.8…
Precise Masses and Orbits for Nine Radial Velocity Exoplanets
Yiting Li, Timothy D. Brandt, G. Mirek Brandt +6
Radial velocity (RV) surveys have discovered hundreds of exoplanetary systems but suffer from a fundamental degeneracy between planet mass and orbital inclination . In thi…
Precise Dynamical Masses and Orbital Fits for Pic b and Pic c
G. Mirek Brandt, Timothy D. Brandt, Trent J. Dupuy +2
We present a comprehensive orbital analysis to the exoplanets Pictoris b and c that resolves previously reported tensions between the dynamical and evolutionary mass constraint…
