JWST spectral retrieval of cold directly imaged planet WD0806 b and the first measurement of altitude-dependent K in exoplanet atmospheres

Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +10

WD0806 b is a rare exoplanet companion orbiting a white dwarf, currently with a projected orbital distance of 2500 au. The Spitzer mid-IR photometry suggests that the temperature i…

Jupiter-like uniform metal enrichment in a system of multiple giant exoplanets

Jean-Baptiste Ruffio, Jerry W. Xuan, Yayaati Chachan +15

The accretion of icy and rocky solids during the formation of a gas giant planet is poorly constrained and challenging to model. Refractory species, like sulfur, are only present i…

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…

Probing the Outskirts of M Dwarf Planetary Systems with a Cycle 1 JWST NIRCam Coronagraphy Survey

Ellis Bogat, Joshua E. Schlieder, Kellen D. Lawson +18

The population of giant planets on wide orbits around low-mass M dwarf stars is poorly understood, but the unprecedented sensitivity of JWST NIRCam coronagraphic imaging now provid…

Investigating the eccentricity distribution of transiting, long-period giant planets

Ahlam Alqasim, Teruyuki Hirano, Yasunori Hori +12

Eccentric giant planets are predicted to have acquired their eccentricity through two major mechanisms: the Kozai-Lidov effect or planet-planet scattering, but it is normally diffi…

JWST-TST High Contrast: Living on the Wedge, or, NIRCam Bar Coronagraphy Reveals CO in the HR 8799 and 51 Eri Exoplanets' Atmospheres

William O. Balmer, Jens Kammerer, Laurent Pueyo +19

High-contrast observations with JWST can reveal key composition and vertical mixing dependent absorption features in the spectra of directly imaged planets across the 3-5 m wave…
