Worlds Next Door. V. A Candidate Solar System Scale Super-Jupiter in the 61 Cygni Binary System
Aniket Sanghi, Billy Quarles, Andrea S. J. Lin +16
We present new constraints on a candidate third companion in the 61 Cygni binary system-one of the closest neighbors to our solar system (3.5 pc), the first stars to have a measure…
JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates
G. Cugno, M. Benisty, R. Teague +32
Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We pr…
A semi-analytical surrogate model for giant planet evolution: bypassing ordinary differential equation solvers with localised thermodynamics, softplus asymptotes, and B-spline photometry
Christian Wilkinson, Jonas Wehrung-Montpezat, Benjamin Charnay +7
Context. Evolutionary models translate the observable luminosity, temperature, and colours of giant planets and brown dwarfs into mass and age. Generating their cooling tracks norm…
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…
Direct Images of CO2 Absorption in the Atmosphere of a Super-Jupiter: Enhanced Metallicity Suggestive of Formation in a Disk
William O. Balmer, Laurent Pueyo, Ashley Messier +15
It is unclear how directly imaged substellar companions with masses near the deuterium burning limit form, because these objects are rare and their bulk properties are not diagnost…
Panchromatic View of the Frigid Jovian Exoplanet COCONUTS-2 b
Matthieu Ravet, Mickaël Bonnefoy, Gaël Chauvin +24
We use a high signal-to-noise MIRI-LRS spectrum (5.45 - 11 m, R ) of COCONUTS-2~b revealing prominent molecular features of HO, CH and NH. This dataset…
A second visit to Eps Ind Ab with JWST: new photometry confirms ammonia and suggests thick clouds in the exoplanet atmosphere of the closest super-Jupiter
Elisabeth C. Matthews, James Mang, Aarynn L. Carter +9
With JWST, we are directly imaging cold (~200-300K), solar-age giant exoplanets for the first time. At these temperatures many molecular features appear and water-ice clouds may co…
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 …
