An efficient Monte Carlo model for the slowing down of photoelectrons. Application to H- in exoplanet atmospheres
Antonio García Muñoz
Photoelectrons, the fast electrons produced in the photoionization of planetary atmospheres, drive transformations in the atmospheric gas that are often inhibited by energy conside…
Signatures of Strong Magnetization and Metal-Poor Atmosphere for a Neptune-Size Exoplanet
Lotfi Ben-Jaffel, Gilda E. Ballester, Antonio García Muñoz +10
The magnetosphere of an exoplanet has yet to be unambiguously detected. Investigations of star-planet interaction and neutral atomic hydrogen absorption during transit to detect ma…
Detection of Paschen absorption in the atmosphere of KELT-9 b: A new window into the atmospheres of ultra-hot Jupiters
A. Sánchez-López, L. Lin, I. A. G. Snellen +4
Hydrogen and helium transmission signals trace the upper atmospheres of hot gas-giant exoplanets, where the incoming stellar extreme ultraviolet and X-ray fluxes are deposited. Fur…
Identification of carbon dioxide in an exoplanet atmosphere
The JWST Transiting Exoplanet Community Early Release Science Team, Eva-Maria Ahrer, Lili Alderson +129
Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the metal enrichment (i.…
HD 56414 b: A Warm Neptune Transiting an A-type Star
Steven Giacalone, Courtney D. Dressing, Antonio García Muñoz +17
We report the discovery in TESS data and validation of HD 56414 b (a.k.a. TOI-1228 b), a Neptune-size () planet with a 29-day orbital period t…
Reflectivity of Venus' dayside disk during the 2020 observation campaign: outcomes and future perspectives
Yeon Joo Lee, Antonio García Muñoz, Atsushi Yamazaki +28
We performed a unique Venus observation campaign to measure the disk brightness of Venus over a broad range of wavelengths in August and September 2020. The primary goal of the cam…
