Heating, Excitation, Dissociation, and Ionization of Molecules by High-Energy Photons in Planetary Atmospheres
Antonio García Muñoz, Ewan Bataille
Photoionization by high-energy photons creates nonthermal electrons with a broad range of energies that heat and chemically transform the atmospheres of planets. The specifics of t…
Dynamics and Clouds in Planetary Atmospheres from Telescopic Observations
Agustín Sánchez-Lavega, Patrick Irwin, Antonio García Muñoz
This review presents an insight into our current knowledge of the atmospheres of the planets Venus, Mars, Jupiter, Saturn, Uranus and Neptune, the satellite Titan, and those of exo…
Hydrodynamic atmospheric escape in HD 189733 b: Signatures of carbon and hydrogen measured with the Hubble Space Telescope
Leonardo A. Dos Santos, Antonio García Munõz, David K. Sing +10
One of the most well-studied exoplanets to date, HD 189733 b, stands out as an archetypal hot Jupiter with many observations and theoretical models aimed at characterizing its atmo…
Detection of the tidal deformation of WASP-103b at with CHEOPS
S. C. C. Barros, B. Akinsanm, G. Boué +5
WASP-103b is the exoplanet with the highest expected deformation signature in its transit light curve and one of the shortest expected spiral-in times. Measuring the tidal deformat…
HST PanCET program: Non-detection of atmospheric escape in the warm Saturn-sized planet WASP-29 b
L. A. dos Santos, V. Bourrier, D. Ehrenreich +10
(Abridged) Short-period gas giant exoplanets are susceptible to intense atmospheric escape due to their large scale heights and strong high-energy irradiation. This process is thou…
Investigation of UV absorbers on Venus using the 283 and 365 nm phase curves obtained from Akatsuki
Y. J. Lee, A. García Muñoz, A. Yamazaki +3
The so-called unknown absorber in the clouds of Venus is an important absorber of solar energy, but its vertical distribution remains poorly quantified. We analyze the 283 and 365-…
The CHEOPS mission
Willy Benz, Christopher Broeg, Andrea Fortier +107
The CHaracterising ExOPlanet Satellite (CHEOPS) was selected in 2012, as the first small mission in the ESA Science Programme and successfully launched in December 2019. CHEOPS is…
Effect of mantle oxidation state and escape upon the evolution of Earth's magma ocean atmosphere
Nisha Katyal, Gianluigi Ortenzi, John Lee Grenfell +7
The magma ocean period was a critical phase determining how Earth atmosphere developed into habitability. However there are major uncertainties in the role of key processes such as…
Transmission Spectroscopy of WASP-79b from 0.6 to 5.0 m
Kristin S. Sotzen, Kevin B. Stevenson, David K. Sing +18
As part of the PanCET program, we have conducted a spectroscopic study of WASP-79b, an inflated hot Jupiter orbiting an F-type star in Eridanus with a period of 3.66 days. Building…
Rapid escape of ultra-hot exoplanet atmospheres driven by Hydrogen Balmer absorption
A. García Muñoz, P. C. Schneider
Atmospheric escape is key to explaining the long-term evolution of planets in our Solar System and beyond, and in the interpretation of atmospheric measurements. Hydrodynamic escap…
The HST PanCET Program: Exospheric Mg II and Fe II in the Near-UV transmission spectrum of WASP-121b using Jitter Decorrelation
David K. Sing, Panayotis Lavvas, Gilda E. Ballester +17
We present HST near-ultraviolet (NUV) transits of the hot Jupiter WASP-121b, acquired as part of the PanCET program. Time series spectra during two transit events were used to meas…
Characterizing the atmosphere of Proxima b with a space-based mid-infrared nulling interferometer
D. Defrère, A. Léger, O. Absil +9
Proxima b is our nearest potentially rocky exoplanet and represents a formidable opportunity for exoplanet science and possibly astrobiology. With an angular separation of only 35~…
