Distinct Rotational Evolution of Giant Planets and Brown Dwarf Companions
Chih-Chun Hsu, Jason J. Wang, Jerry W. Xuan +27
We present a rotational velocity (vsini) survey of 32 stellar/substellar objects and giant planets using Keck/KPIC high-resolution spectroscopy, including 6 giant planets (2-7 M$_\…
Fringing analysis and forward modeling of Keck Planet Imager and Characterizer (KPIC) spectra
Katelyn A. Horstman, Jean-Baptiste Ruffio, Jason J. Wang +27
The Keck Planet Imager and Characterizer (KPIC) combines high contrast imaging with high resolution spectroscopy (R~35,000 in K band) to study directly imaged exoplanets and brown…
Water dissociation and rotational broadening in the atmosphere of KELT-20 b from high-resolution spectroscopy
Luke Finnerty, Yinzi Xin, Jerry W. Xuan +29
We present atmospheric retrievals from Keck/KPIC phase II observations of the ultra-hot Jupiter KELT-20/MASCARA-2~b. Previous free retrievals of molecular abundances for ultra-hot…
Technical description and performance of the phase II version of the Keck Planet Imager and Characterizer
Nemanja Jovanovic, Daniel Echeverri, Jacques-Robert Delorme +46
The Keck Planet Imager and Characterizer (KPIC) is a series of upgrades for the Keck II Adaptive Optics (AO) system and the NIRSPEC spectrograph to enable diffraction limited, high…
RV measurements of directly imaged brown dwarf GQ Lup B to search for exo-satellites
Katelyn Horstman, Jean-Baptiste Ruffio, Konstantin Batygin +35
GQ Lup B is one of the few substellar companions with a detected cicumplanetary disk, or CPD. Observations of the CPD suggest the presence of a cavity, possibly formed by an exo-sa…
Atmospheric characterization of the super-Jupiter HIP 99770 b with KPIC
Yapeng Zhang, Jerry W. Xuan, Dimitri Mawet +28
Young, self-luminous super-Jovian companions discovered by direct imaging provide a challenging test of planet formation and evolution theories. By spectroscopically characterizing…
