Correcting Exoplanet Transmission Spectra for Stellar Activity with an Optimized Retrieval Framework

The chromatic contamination that arises from photospheric heterogeneities, e.g., spots and faculae on the host star presents a significant noise source for exoplanet transmission spectra. If this contamination is not corrected for, it can introduce substantial bias in our analysis of the planetary a...
