The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future

Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123

JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…

JWST-TST High Contrast: First Direct Spectroscopy of GJ 504 b reveals Clouds and Possible Metal Enrichment

Aneesh Baburaj, Jean-Baptiste Ruffio, Marshall Perrin +27

Characterizing the coldest directly imaged companions through direct spectroscopy has only recently become possible with the James Webb Space Telescope. We present moderate-resolut…

Water ice in the debris disk around HD 181327

Chen Xie, Christine H. Chen, Carey M. Lisse +13

Debris disks are exoplanetary systems that contain planets, minor bodies (i.e., asteroids, Kuiper belt objects, comets, etc.), and micron-sized debris dust. Since water ice is the…

JWST-TST High Contrast: Medium-resolution spectroscopy reveals a carbon-rich circumplanetary disk around the young accreting exoplanet Delorme 1 AB b

Mathilde Mâlin, Kimberly Ward-Duong, Sierra L. Grant +21

Young accreting planetary-mass objects are thought to draw material from a circumplanetary disk (CPD) composed of gas and dust. While the gas within the disk is expected to dispers…

JWST/NIRSpec Detects Warm CO Emission in the Terrestrial-Planet Zone of HD 131488

Cicero X. Lu, Isabel Rebollido, Sean Brittain +12

We have obtained a high-resolution, JWST NIRSpec -- m spectrum of the debris disk around HD 131488. We discover CO fundamental emission indicating the presence of…

Probing the era of giant collisions: millimeter observations of the HD 166191 system

Kadin Worthen, Christine H. Chen, A. Meredith Hughes +5

We present non-simultaneous ALMA band 7 and SMA observations of the HD 166191 disk, which was recently thought to have a collision in its terrestrial planet zone. Both observations…
