About this technology
Overview
The high-contrast imaging technique is meant to provide insight into those planets orbiting several astronomical units from their host star. Space missions such as Nancy Grace Roman Space Telescope and the Habitable World Observatory will measure reflected light spectra of cold gaseous and rocky planets. To interpret these observations, we introduce ExoReL^R (Exoplanetary Reflected Light Retrieval), a Bayesian retrieval framework to retrieve cloud properties and atmospheric structures from exoplanetary refleected light spectra. As a unique feature, it assumes a vertically nonuniform volume mixing ratio (VMR) profile of water and ammonia, and uses it to construct cloud densities. In this way, clouds and molecular mixture ratios are consistent
