Title: From Exoplanets to Exoworlds: Atmospheric Characterization with KOSMOS

Abstract: \vspace*{-0.8\baselineskip} Recent surveys have revealed an amazing yet unexplained diversity of planets orbiting other stars. Studying the atmospheres of a representative sample of exoplanets is the next step in leveraging these detections to further transform our understanding of planetary physics. However, revealing the fundamental properties of exoplanet atmospheres requires high-precision spectroscopy of a large number of targets. Such data can only be obtained with 4-meter-class telescopes because they offer the appreciable number of nights needed for a large-scale, atmospheric-characterization program. As a proof-of-concept, we propose to use KOSMOS in the blue optical to perform multi-object spectroscopy observations of one of two transiting exoplanets to identify the condensate species responsible for the presence of clouds. Understanding the prevalence of hazes and aerosols at different temperatures and surface gravities is one of the major outstanding issues in exoplanetary atmospheres. Upon successful validation of KOSMOS, we will propose for a more ambitious, multi-year survey program in which our goal is to create a catalog of atmospheric constraints as a function of planet properties.
