Diversity in the haziness and chemistry of temperate sub-Neptunes
Pierre-Alexis Roy, Björn Benneke, Marylou Fournier-Tondreau +17
Recent transit observations of K2-18b and TOI-270d revealed strong molecular absorption signatures, lending credence to the idea that temperate sub-Neptunes (T=250-40…
Reanalysis of the eclipses of LHS 1140 c: No evidence of an atmosphere and implications for the internal structure of the planet
Alexandra Rochon, Étienne Artigau, Drew Weisserman +4
We present the reanalysis of three 15 micron JWST/MIRI secondary eclipses of LHS 1140 c, a warm super-Earth (R = 1.272 R) in a 3.78-day orbit around an M4.5 d…
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…
A Thick Volatile Atmosphere on the Ultrahot Super-Earth TOI-561 b
Johanna K. Teske, Nicole L. Wallack, Anjali A. A. Piette +10
Ultrashort-period (USP) exoplanets -- with R and periods 1 day -- are expected to be stripped of volatile atmospheres by intense host star irradiation…
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…
On the synergetic use of Ariel and JWST for exoplanet atmospheric science
Quentin Changeat, Pierre-Olivier Lagage, Giovanna Tinetti +27
This paper explores the potential for strategic synergies between the JWST and the Ariel telescopes, two flagship observatories poised to revolutionise the study of exoplanet atmos…
