Searching for Planets Orbiting ~Eridani with JWST/NIRCam

Jorge Llop-Sayson, Charles Beichman, Geoffrey Bryden +10

We present observations of \epseri~with the JWST/NIRCam coronagraph aimed at imaging planets orbiting within this system. In particular, these observations targeted (1) the Jupiter…

A planetary-mass candidate imaged in the Young Suns Exoplanet Survey

Pengyu Liu, Matthew A. Kenworthy, Beth A. Biller +26

Directly imaged exoplanets in wide orbits challenge current gas giant formation theories. They need to form quickly and acquire enough material before the disk dissipates, which ca…

A Survey of Protoplanetary Disks Using the Keck/NIRC2 Vortex Coronagraph

Nicole L. Wallack, Jean-Baptiste Ruffio, Garreth Ruane +34

Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spira…

Planet Search with the Keck/NIRC2 Vortex Coronagraph in Ms-band for Vega

Bin B. Ren, Nicole L. Wallack, Spencer A. Hurt +12

Gaps in circumstellar disks can signal the existence of planetary perturbers, making such systems preferred targets for direct imaging observations of exoplanets. Being one of the…

Unveiling wide-orbit companions to K-type stars in Sco-Cen with Gaia EDR3

Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +12

Abbreviated. We aim to identify new low-mass companions to young stars using the astrometric measurements provided by the Gaia space mission and complementary VLT/SPHERE data. We i…

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…
