Discovery of an Exterior Third Planet Orbiting Pictoris

Aidan Gibbs, Jean-Baptiste Ruffio, Alexis Bidot +9

We report the discovery of Pictoris d ( Pic d), a third giant planet in the Pictoris system, which now becomes only the second directly imaged system with more than two…

Simulations of Flare Chemistry in Brown Dwarf Companions to Active M Dwarfs

Aidan Gibbs, Michael P. Fitzgerald

Brown dwarfs that are short period (day) companions to actively flaring M dwarfs may provide a context to directly observe flare-driven photochemistry and structural changes…

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…

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…
