Large ground- and space-based telescopes will be able to observe Earth-like
planets in the near future. We explore how different planetary surfaces can
strongly influence the climate, atmospheric composition, and remotely
detectable spectra of terrestrial rocky exoplanets in the habitable zone
depending on the host star’s incident irradiation spectrum for a range of
Sun-like host stars from F0V to K7V. We update a well-tested 1D
climate-photochemistry model to explore the changes of a planetary environment
for different surfaces for different host stars. Our results show that using a
wavelength-dependent surface albedo is critical for modeling potentially
habitable rocky exoplanets.
