Leaning Sideways: VHS 1256-1257 b is a Super-Jupiter with a Uranus-like Obliquity
Michael Poon, Marta L. Bryan, Hanno Rein +4
We constrain the angular momentum architecture of VHS J125601.92-125723.9, a 140 20 Myr old hierarchical triple system composed of a low-mass binary and a widely-separated pl…
Efficiently Searching for Close-in Companions around Young M Dwarfs using a Multi-year PSF Library
Aniket Sanghi, Jerry Xuan, Jason Wang +7
We present Super-RDI, a unique framework for the application of reference star differential imaging (RDI) to Keck/NIRC2 high-contrast imaging observations with the vortex coronagra…
Are these planets or brown dwarfs? Broadly solar compositions from high-resolution atmospheric retrievals of ~10-30 companions
Jerry W. Xuan, Chih-Chun Hsu, Luke Finnerty +32
Using Keck Planet Imager and Characterizer (KPIC) high-resolution (~35000) spectroscopy from 2.29-2.49 m, we present uniform atmospheric retrievals for eight young substellar…
kappa And b is a fast rotator from KPIC High Resolution Spectroscopy
Evan C. Morris, Jason J. Wang, Chih-Chun Hsu +24
We used the Keck Planet Imager and Characterizer (KPIC) to obtain high-resolution (R35,000) K-band spectra of kappa Andromedae b, a planetary-mass companion orbiting the B9V…
Friends not Foes: Strong Correlation between Inner Super-Earths and Outer Gas Giants
Marta L. Bryan, Eve J. Lee
The connection between outer gas giants and inner super-Earths reflects their formation and evolutionary histories. Past work exploring this link has suggested a tentative positive…
Atmospheric Retrievals of the Young Giant Planet ROXs 42B b from Low- and High-Resolution Spectroscopy
Julie Inglis, Nicole L. Wallack, Jerry W. Xuan +7
Previous attempts have been made to characterize the atmospheres of directly imaged planets at low-resolution (R10s-100s), but the presence of clouds has often led to degener…
