A New Model Suite to Determine the Influence of Cosmic Rays on (Exo)planetary Atmospheric Biosignatures -- Validation based on Modern Earth
Konstantin Herbst, John Lee Grenfell, Miriam Sinnhuber +8
The first opportunity to detect indications for life outside the Solar System may be provided already within the next decade with upcoming missions such as the James Webb Space Tel…
Unveiling shrouded oceans on temperate sub-Neptunes via transit signatures of solubility equilibria vs. gas thermochemistry
Renyu Hu, Mario Damiano, Markus Scheucher +3
The recent discovery and initial characterization of sub-Neptune-sized exoplanets that receive stellar irradiance of approximately Earth's raised the prospect of finding habitable…
A secondary atmosphere on the rocky exoplanet 55 Cancri e
Renyu Hu, Aaron Bello-Arufe, Michael Zhang +14
Characterizing rocky exoplanets is a central endeavor of astronomy, and yet the search for atmospheres on rocky exoplanets has hitherto resulted in either tight upper limits on the…
Atmospheric processes affecting methane on Mars
John Lee Grenfell, Fabian Wunderlich, Miriam Sinnhuber +6
It is currently uncertain as to whether methane exists on Mars. Data from the Curiosity Rover suggests a background methane concentration of a few tenths parts per billion whereas…
New Insights into Cosmic Ray induced Biosignature Chemistry in Earth-like Atmospheres
Markus Scheucher, J. L. Grenfell, F. Wunderlich +3
With the recent discoveries of terrestrial planets around active M-dwarfs, destruction processes masking the possible presence of life are receiving increased attention in the exop…
The PAC2MAN mission: a new tool to understand and predict solar energetic events
Jorge Amaya, Sophie Musset, Viktor Andersson +12
An accurate forecast of flare and CME initiation requires precise measurements of the magnetic energy build up and release in the active regions of the solar atmosphere. We designe…
