Hydrocarbon Hazes on Temperate sub-Neptune K2-18b supported by data from the James Webb Space Telescope
Ruohan Liu, Panayotis Lavvas, Giovanna Tinetti +3
K2-18b, a sub-Neptune orbiting in the habitable zone of an M dwarf, has attracted significant interest following observations with the Hubble Space Telescope (HST) and, more recent…
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…
Helium escape in context: Comparative signatures of four close-in exoplanets
Anna Ruth Taylor, Tommi T. Koskinen, Chenliang Huang +2
Observations of escaping atmospheres on close-in exoplanets show a wide range in the strength and morphology of He I 10830 A and H I absorption. Scaling relations attempt to link t…
Using SOFIA's EXES to search for CH and CN in Titan's atmosphere
Zachary C. McQueen, Conor A. Nixon, Curtis de Witt +7
In Titan's atmosphere, the chemistry of small hydrocarbons and nitriles represent an important link from molecular species to the ubiquitous organic haze that gives Titan its chara…
A Multi-Species Atmospheric Escape Model with Excited Hydrogen and Helium: Application to HD209458b
Anna Ruth Taylor, Tommi T. Koskinen, Luca Argenti +4
Atmospheric escape shapes exoplanet evolution and star-planet interactions, with He I 10830 Ã absorption serving as a key tracer of mass loss in hot gas giants. However, transit de…
