Spectra of Earth-like planets through geological evolution around FGKM stars

Abstract:

Future observations of terrestrial exoplanet atmospheres will occur for planets at different stages of geological evolution. We expect to observe a wide variety of atmospheres and planets with alternative evolutionary paths, with some planets resembling Earth at different epochs. For an Earth-like atmospheric time trajectory, we simulate planets from the prebiotic to the current atmosphere based on geological data. We use a stellar grid F0V to M8V (${T}_{\mathrm{eff}}=7000$–2400 K) to model f...
