High-resolution Ultraviolet-to-nearinfrared Characterization of Exoplanet Atmospheres
Patricio E. Cubillos, Matteo Brogi, Antonio García Muñoz +19
The Habitable Worlds Observatory (HWO) offers a unique opportunity to revolutionize our understanding of planetary formation and evolution. The goal of this Science Case Developmen…
A 3D model simulation of hydrogen chloride photochemistry on Mars: Comparison with satellite data
Benjamin Benne, Paul I. Palmer, Benjamin M. Taysum +2
HCl was detected in the Martian atmosphere by the NOMAD and ACS spectrometers aboard the ExoMars TGO. Photochemical models show that using gas-phase chemistry alone is insufficient…
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…
