A Chemical Modeling Roadmap Linking Protoplanetary Disks and Exoplanet Atmospheres

Exoplanet atmospheres and protoplanetary disk chemistry are both active fields of research. Chronologically, they represent opposite ends the process planet formation: planets form in disks, composition their should reflect material from. The past decade discoveries insights by ALMA observatory has provided a quantum leap our understanding structures chemical compositions disks. Likewise, ground- space-based facilities have peeks into exoplanet atmospheres. However, near future, with, first foremost, James Webb Space Telescope, later also ESO’s Extremely Large Telescope ESA’s Ariel mission expected to constraints on atmospheric with unprecedented precision and, also, shed new light gas ice It is therefore timely evaluate current state modeling efforts attempting link formation compositions. author background astrochemistry related formation.
