A Sulfur-Rich Atmosphere for the Young Jupiter Analog AF Lep b Reveals Significant Solid Accretion
Jerry W. Xuan, William O. Balmer, Yayaati Chachan +25
AF Lep b is one of the closest analogs to Jupiter in terms of mass () and semi-major axis ( AU) amenable to spectroscopic characterization. We present JWST/NIR…
Discovery of an Exterior Third Planet Orbiting Pictoris
Aidan Gibbs, Jean-Baptiste Ruffio, Alexis Bidot +9
We report the discovery of Pictoris d ( Pic d), a third giant planet in the Pictoris system, which now becomes only the second directly imaged system with more than two…
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…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems. VII. Molecular Mapping Performance with JWST/MIRI MRS: VHS 1256 b as a case study
Mathilde Mâlin, Anthony Boccaletti, Benjamin Charnay +29
VHS 1256 b was the first planetary-mass companion to be observed with the James Webb Space Telescope's Mid-Infrared Instrument (JWST/MIRI) using the Medium-Resolution Spectrometer…
Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for Ind Ab
Aniket Sanghi, William Thompson, James Mang +21
We present new JWST/NIRCam 4-5 m (F410M, F430M) and JWST/MIRI 18-25 m (F1800W, F2100W, F2550W) imaging detections of the nearby (3.6 pc) cold (275 K) gas giant exoplanet …
Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. II. Binary Star Modeling, Planet and Exozodi Search, and Sensitivity Analysis
Aniket Sanghi, Charles Beichman, Dimitri Mawet +14
JWST observed our closest solar twin, Cen A, with the MIRI coronagraph in F1550C (15.5 m) at three distinct epochs between August 2024 and April 2025. For the first time wit…
Visible extreme adaptive optics on extremely large telescopes: Towards detecting oxygen in Proxima Centauri b and analogs
J. Fowler, Sebastiaan Y. Haffert, Maaike A. M. van Kooten +38
Looking to the future of exo-Earth imaging from the ground, core technology developments are required in visible extreme adaptive optics (ExAO) to enable the observation of atmosph…
Chasing rainbows and ocean glints: Inner working angle constraints for the Habitable Worlds Observatory
Sophia R. Vaughan, Timothy D. Gebhard, Kimberly Bott +41
NASA is engaged in planning for a Habitable Worlds Observatory (HabWorlds), a coronagraphic space mission to detect rocky planets in habitable zones and establish their habitabilit…
