Venus as an Exoplanet: Effect of varying stellar, orbital, planetary and atmospheric properties upon composition, habitability and detectability — •John Lee Grenfell1, Jörn Helbert1, Gabriele Arnold1, Konstantin Herbst2, Miriam Sinnhuber3, and Heike Rauer1,4 — 1Department of Extrasolar Planets and Atmospheres (EPA), German Aerospace Centre, Berlin — 2Centre for Planetary Habitability, University of Oslo — 3Institute for Meteorology and Climate Research, Karlsruhe Institute of Technologie (KIT) — 4Institute for Geological Sciences, Free University of Berlin
The newly selected Venus missions EnVISION and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) offer new opportunities for studying Venus but will also contribute to furthering our knowledge of Venus as an exoplanet. Hot rocky planets are favored targets due to generally more frequent transits than cooler Earth-like objects. In this work we simulate Venus as an exoplanet varying stellar, orbital, planetary and atmospheric parameters and study the effect upon atmospheric composition, climate and spectral detectability with the LIFE (Large Interferometer For Exoplanets) telescope.
Keywords: Venus; exoplanet; atmosphere; habitability; biosignatures
