Self-consistent 1D modelling of Jupiter's upper atmosphere as an exoplanet analogue

Nils-Martin Robeling, Sudeshna Boro Saikia, Gwenaëlle Van Looveren +5

Jupiter's upper atmosphere provides a real-world laboratory for validating first-principles models of giant gaseous exoplanets and for constraining the key physical processes that…

Star Planet Interactions

Arghyadeep Paul, Kristina Kislyakova, Manuel Güdel +13

Star-planet interactions (SPIs) describe the continuous exchange of energy, momentum, and mass between exoplanets and their host stars through radiative, tidal, magnetic, and parti…

Stellar Forcing of (exo)Planetary Environments

Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13

The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…

Long-term X-ray variability of the multiple-planet host L 98-59: Hints of an activity cycle

I. Pillitteri, S. Bellotti, S. Benatti +7

High-energy irradiation in X-rays and UV (XUV) can transform the planetary atmospheres through photoevaporation and photochemistry. This is more crucial for M stars, whose habitabl…

First Resolution of a Main Sequence G-Star Astrosphere Using Chandra

C. M. Lisse, S. J. Wolk, B. Snios +24

We report resolution of a halo of X-ray line emission surrounding the Zero Age Main Sequence (ZAMS) G8.5V star HD 61005 by Chandra ACIS-S. Located only 36.4 pc distant, HD 61005 is…
