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 t…
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 $Î…
Direct Spectroscopy of 51 Eridani b with JWST NIRSpec
Alexander Madurowicz, Jean-Baptiste Ruffio, Bruce Macintosh +4
We present high-contrast direct spectroscopy of the low-mass, cool exoplanet 51 Eridani b (2-4 M, 750 K) using JWST / NIRSpec in a fixed-slit configuration (F2…
Apache Point Observatory follow-up of ACcelerating Candidate ExopLanet host Stars (APO ACCELS): Ages for 166 Accelerating Stars in the Northern Hemisphere
Anne E. Peck, Eric L. Nielsen, Robert J. De Rosa +14
Directly imaged substellar companions with well-constrained ages and masses serve as vital empirical benchmarks for planet formation and evolution models. Potential benchmark compa…
