Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The paper summarizes 70 science cases for the proposed NASA Habitable Worlds Observatory, outlining the observational needs across four scientific pillars and detailing required ca…
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 NIRCam Reveals the Largest Known M-dwarf Debris Disk Around TWA 10 and New Scattered-Light Observations of the TWA 25 Debris Disk
Katie A. Crotts, Aarynn L. Carter, Beth Biller +26
We present JWST NIRCam observations of two M-dwarf systems located in the TW Hydra association, TWA 10 and TWA 25. Both systems harbor detected debris disks in the F200W and F444W…
Photometric Variability and Rotation of Beta Pictoris b from JWST NIRCam Coronagraphic Imaging
Yifan Zhou, Beth A. Biller, Aarynn L. Carter +30
We report the detection of photometric variability in the directly imaged super-Jupiter Pictoris b. Using JWST NIRCam dual-band coronagraphic imaging, we conducted a 16-hour c…
Probing the origins. III. Exoplanet demographics across Galactic birth radii
Juan José GarcÃa-Delgado, M. L. L. Dantas, Isabel Rebollido +1
We quantify radial mixing in exoplanet hosts and explore links between birth environment, orbital evolution, planetary architecture, and Galactic habitability. We constructed a hom…
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…
