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 Imaging of Young Stellar Objects. IV. Detailed Imaging of the Protoplanetary Disk around TW Hya
Yu-Chia Lin, Jarron Leisenring, Schuyler G. Wolff +14
As the nearest protoplanetary disk to Earth ( pc), TW Hya is one of the most studied protoplanetary disks and a critical benchmark for testing planet formation theories.…
Precise Constraints on the Energy Budget of WASP-121 b from its JWST NIRISS/SOSS Phase Curve
Jared Splinter, Louis-Philippe Coulombe, Robert C. Frazier +20
Ultra-hot Jupiters exhibit day-to-night temperature contrasts upwards of 1000 K due to competing effects of strong winds, short radiative timescales, magnetic drag, and H2 dissocia…
Enriched volatiles and refractories but deficient titanium on the dayside atmosphere of WASP-121b revealed by JWST/NIRISS
Stefan Pelletier, Louis-Philippe Coulombe, Jared Splinter +21
With dayside temperatures elevated enough for all atmospheric constituents to be present in gas form, ultra-hot Jupiters offer a unique opportunity to probe the composition of gian…
A complex structure of escaping helium spanning more than half the orbit of the ultra-hot Jupiter WASP-121\,b
Romain Allart, Louis-Philippe Coulombe, Yann Carteret +19
Atmospheric escape of planets on short orbital periods, driven by the host star's irradiation, influences their evolution, composition, and atmospheric dynamics. Our main avenue to…
Direct Measurement of Extinction in a Planet-Hosting Gap
G. Cugno, S. Facchini, F. Alarcon +12
Recent disk observations have revealed multiple indirect signatures of forming gas giant planets, but high-contrast imaging has rarely confirmed the presence of the suspected pertu…
