WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research

A. G. Sreejith, L. Fossati, M. Lendl +81

Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…

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…
