Hi everyone: We are excited to announce our session at Goldschmidt 2025 in Prague entitled “Chemistry of Exoplanets”. This session is in Theme 2, session 02k. Abstract deadline: February 26 at 2:59 pm Pacific (23:59 CET/UTC +1) Submit an abstract & browse sessions: conf.goldschmidt.info/goldschmidt/2025/cfp.cgi Grant info: conf.goldschmidt.info/goldschmidt/2025/meetingapp.cgi/ModuleMeetingInfo/GrantProgram We invite all abstracts aimed at understanding exoplanets. We strongly encourage submissions from early career researchers and underrepresented groups. Conveners: Kara Brugman (Arizona State University) Maggie Thompson (Carnegie Institution for Science) Full session description: We are at the beginning of an observational revolution in exoplanet science. The advanced capabilities of JWST, ALMA, and upcoming large ground-based observatories will allow us to better characterize physical properties of exoplanets, their atmospheres, and their host stars. This information will allow us to place Earth and our solar system’s other rocky bodies in the wider context of planet formation and evolution in the universe. Based on our current understanding, the most common types of planets are sub-Neptunes and super-Earth (planets with masses in between those of Earth and Neptune) for which we have no analog in our Solar System. The chemical properties of exoplanets are expected to be diverse, from their interior structures to their atmospheric compositions, all of which are shaped by the chemical environment in protoplanetary disks and subsequently modified by processes throughout a planet’s evolution. A comprehensive understanding of exoplanet demographics and of what exoplanets are likely to be habitable requires interdisciplinary knowledge across geochemistry, meteoritics and cosmochemistry, astronomy, planetary science, mineral physics, biogeochemistry, and extremophile biology. In this session, we invite contributions spanning theoretical, experimental and observational research that seeks to improve our understanding of the chemical properties of exoplanets and protoplanetary disks. ––––– Kara Brugman, Ph.D. (pronunciation; s/h) FORCE, Arizona State University kara.brugman@asu.edu // karabrugman.com AZ does not observe DST - check current time in AZ
