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…
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…
Evolution of Earth-like planetary atmospheres around M-dwarf stars: Assessing the atmospheres and biospheres with a coupled atmosphere biogeochemical model
S. Gebauer, J. L. Grenfell, R. Lehmann +1
Earth-like planets orbiting M-dwarfs are prominent future targets when searching for life outside the solar system. We apply our newly developed Coupled Atmosphere Biogeochemistry…
Evolution of Earth-like extrasolar planetary atmospheres: Assessing the atmospheres and biospheres of early Earth analog planets with a coupled atmosphere biogeochemical model
S. Gebauer, J. L. Grenfell, J. W. Stock +4
Understanding the evolution of Earth and potentially habitable Earth-like worlds is essential to fathom our origin in the Universe. The search for Earth-like planets in the habitab…
Limitation of atmospheric composition by combustion-explosion in exoplanetary atmospheres
John Lee Grenfell, Stefanie Gebauer, Mareike Godolt +3
This work presents theoretical studies which combine aspects of combustion and explosion theory with exoplanetary atmospheric science. Super Earths could possess a large amount of…
Potential Biosignatures in Super-Earth Atmospheres II. Photochemical Responses
J. L. Grenfell, S. Gebauer, M. Godolt +6
Spectral characterization of Super-Earth atmospheres for planets orbiting in the Habitable Zone of M-dwarf stars is a key focus in exoplanet science. A central challenge is to unde…
