Retrieving the C and O Abundances of HR 7672~AB: a Solar-Type Primary Star with a Benchmark Brown Dwarf
Ji Wang, Jared R. Kolecki, Jean-Baptiste Ruffio +30
A benchmark brown dwarf (BD) is a BD whose properties (e.g., mass and chemical composition) are precisely and independently measured. Benchmark BDs are valuable in testing theoreti…
An Imaging Search for Post-Main-Sequence Planets of Sirius B
Miles Lucas, Michael Bottom, Garreth Ruane +1
We present deep imaging of Sirius B, the closest and brightest white dwarf, to constrain post-main-sequence planetary evolution in the Sirius system. We use Keck/NIRC2 in L'-band (…
Detection and Bulk Properties of the HR 8799 Planets with High Resolution Spectroscopy
Jason J. Wang, Jean-Baptiste Ruffio, Evan Morris +49
Using the Keck Planet Imager and Characterizer (KPIC), we obtained high-resolution (R35,000) -band spectra of the four planets orbiting HR 8799. We clearly detected \water…
Analysis of Neptune's 2017 Bright Equatorial Storm
Edward Molter, Imke de Pater, Statia Luszcz-Cook +22
We report the discovery of a large (8500 km diameter) infrared-bright storm at Neptune's equator in June 2017. We tracked the storm over a period of 7 months with high-cadenc…
Characterizing the performance of the NIRC2 vortex coronagraph at W.M. Keck Observatory
W. Jerry Xuan, Dimitri Mawet, Henry Ngo +15
The NIRC2 vortex coronagraph is an instrument on Keck II designed to directly image exoplanets and circumstellar disks at mid-infrared bands (3.4-4.1 m) and (4.…
