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…
Demonstrating Exoplanet Transit Photometry from Space with a 15-mm Aperture Optical Navigation Camera on Hayabusa2
Koki Yumoto, Toru Kouyama, Manabu Yamada +14
Observations of exoplanet transits by small satellites have gained increasing attention for reducing detection biases. However, no unambiguous detection of an exoplanet has yet bee…
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 Å absorption serving as a key tracer of mass loss in hot gas giants. However, transit de…
Atmospheric characterisation of GJ1214b from transit and eclipse observations
Panayotis Lavvas, Sophia Paraskevaidou, Anthony Arfaux
The atmospheric characterisation of GJ1214 b has so far remained uncertain due to the observed flatness of the transit spectra of this planet that is typically attributed to the pr…
Coupling haze and cloud microphysics in WASP-39b's atmosphere based on JWST observations
Anthony Arfaux, Panayotis Lavvas
We present a study on the coupling of haze and clouds in the atmosphere of WASP-39b. We developed a cloud microphysics model simulating the formation of Na2S and MgSiO3 condensates…
A physically derived eddy parameterization for giant planet atmospheres with application on hot-Jupiter atmospheres
Anthony Arfaux, Panayotis Lavvas
We present a parameterization for the eddy diffusion profile of gas giant exoplanets based on physical phenomena and we explore how the parameterized eddy profile impacts the chemi…
A large range of haziness conditions in hot-Jupiter atmospheres
Anthony Arfaux, Panayotis Lavvas
We present a study of photochemical hazes of exoplanet atmospheres based on a self-consistent model including haze microphysics, disequilibrium chemistry, and radiative feedbacks.…
Impact of photochemical hazes and gases on exoplanet atmospheric thermal structure
Panayotis Lavvas, Anthony Arfaux
We investigate the impact of photochemical hazes and disequilibrium gases on the thermal structure of hot-Jupiters, using a detailed 1-D radiative-convective model. We find that th…
