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…

Influence of Biomass Emissions upon Habitability, Biosignatures and Detectability in Earth-like Atmospheres

Stefanie Gebauer, Iva Vilović, John Lee Grenfell +3

We investigate atmospheric responses of modeled hypothetical Earth-like planets in the habitable zone of the M-dwarf AD Leonis to reduced oxygen (O2), removed biomass (dead Earth),…

Detectability of atmospheric features of Earth-like planets in the habitable zone around M dwarfs

F. Wunderlich, M. Godolt, J. L. Grenfell +6

We investigate the detectability of atmospheric spectral features of Earth-like planets in the habitable zone (HZ) around M dwarfs with the future James Webb Space Telescope (JWST)…

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…
