Paper III of the LIFE paper series accepted for publication in A&A
In Konrad et al. (link to arxiv), the LIFE team derived first constraints on the technical requirements for the LIFE telescope. We ran Bayesian atmospheric retrievals for different quality thermal emission spectra of an Earth-twin exoplanet. By analyzing how well the retrieval can characterize Earth (e.g. radius, see Figure left) and its atmosphere (e.g. trace gas abundances, see Figure right) for different quality spectra via retrievals, we derive minimal requirements for LIFE’s wavelength coverage, spectral resolution, and signal-to-noise ratio.
