Exoplanet Atmospheric Composition: a Tracer of Formation Processes
Mark Swain (JPL)

Abstract: That planets are ubiquitous is now well established but the details of the formation mechanism are not well understood. Theoretical studies suggest that the process of planet formation may leave an imprint on exoplanet atmospheres. When not substantially modified by subsequent evolution, atmospheric composition has the potential to reveal the critical aspects of the planet formation process. The opportunity to probe planet formation in this manor must be balanced with the tremendous diversity that exists for exoplanets – this requires a statistical approach. Transiting planets are well suited for a large-scale, uniform survey; currently we know of more than 2500 transiting planets and TESS is poised to find at least 1500 more around bright stars. Building the success of Kepler and TESS, a large spectroscopic survey of transiting exoplanets would make a decisive contribution to our understanding of planet formation.
