The effect of a biosphere on the habitable timespan of stagnant-lid planets and implications for the atmospheric spectrum
Dennis Höning, Ludmila Carone, Philipp Baumeister +6
Temperature-dependent biological productivity controls silicate weathering and thereby extends the potential habitable timespan of Earth. Models and theoretical considerations indi…

Detectability of biosignatures in warm, water-rich atmospheres
Benjamin Taysum, Iris van Zelst, John Lee Grenfell +3
Warm rocky exoplanets within the habitable zone of Sun-like stars are favoured targets for current and future missions. Theory indicates these planets could be wet at formation and…

Impact of Cosmic Rays on Atmospheric Ion Chemistry and Spectral Transmission Features of TRAPPIST-1e
Konstantin Herbst, Andreas Bartenschlager, John Lee Grenfell +10
Ongoing observing projects like the James Webb Space Telescope (JWST) and future missions offer the chance to characterize Earth-like exoplanetary atmospheres. Thereby, M-dwarfs ar…
