Different UV spectra for TRAPPIST-1 produce order-of-magnitude variations in CH4, CO, O2, and O3 abundances for Archean-analog TRAPPIST-1 e atmospheres, generating photochemical degeneracies and potential false-positive biosignatures.
Mars provides a real-world case study of processes like volatile loss, climate evolution, and magnetism that determine habitability on small rocky planets at the edge of habitable conditions.
