Atmospheric abundances and bulk properties of the binary brown dwarf Gliese 229 Bab from JWST/MIRI spectroscopy

Jerry W. Xuan, Marshall D. Perrin, Dimitri Mawet +8

We present JWST/MIRI low-resolution spectroscopy (m) of the first known substellar companion, Gliese 229 Bab, which was recently resolved into a tight binary brown dwarf…

A High-Resolution Spectroscopic Survey of Directly Imaged Companion Hosts: I. Determination of diagnostic stellar abundances for planet formation and composition

Aneesh Baburaj, Quinn M. Konopacky, Christopher A. Theissen +6

We present the first results of an extensive spectroscopic survey of directly imaged planet host stars. The goal of the survey is the measurement of stellar properties and abundanc…

Standing on the Shoulders of Giants: A Comprehensive Spectroscopic Survey of Transiting & High-Contrast Giant Planets

Munazza K. Alam, Emily Rickman, Kielan Hoch +6

We propose a comprehensive survey of giant planets ranging from close-in highly irradiated hot Jupiters to young, wide-orbit directly imaged planets. The combination of two establi…

The Unrealised Interdisciplinary Advantage of Observing High Mass Transiting Exoplanets and Brown Dwarfs -- Strategic Exoplanet Initiatives with HST and JWST White Paper

Aarynn L. Carter, Munazza. K. Alam, Thomas Beatty +8

We advocate for further prioritisation of atmospheric characterisation observations of high mass transiting exoplanets and brown dwarfs. This population acts as a unique comparativ…

JWST-TST High Contrast: Spectroscopic Characterization of the Benchmark Brown Dwarf HD 19467 B with the NIRSpec Integral Field Spectrograph

Kielan K. W. Hoch, Christopher A. Theissen, Travis S. Barman +14

We present the atmospheric characterization of the substellar companion HD 19467 B as part of the pioneering JWST GTO program to obtain moderate resolution spectra (R2,700, 3…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems V: Do Self-Consistent Atmospheric Models Represent JWST Spectra? A Showcase With VHS 1256 b

Simon Petrus, Niall Whiteford, Polychronis Patapis +119

The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) com…

MIRI MRS Observations of Beta Pictoris I. The Inner Dust, the Planet, and the Gas

Kadin Worthen, Christine H. Chen, David R. Law +15

We present JWST MIRI Medium Resolution Spectrograph (MRS) observations of the Pictoris system. We detect an infrared excess from the central unresolved point source from 5 to 7…

JWST-TST High Contrast: Asymmetries, dust populations and hints of a collision in the Pictoris disk with NIRCam and MIRI

Isabel Rebollido, Christopher C. Stark, Jens Kammerer +21

We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~m provi…
