One year of JWST: photodissociation regions, protostars, disks, and planets − an EAS 2023 symposium

July 13 @ 08:00 July 14 @ 17:00 Europe/Krakow

Almost 40 years since the Infrared Astronomical Satellite (IRAS) completed the first, full-sky survey, a succession of infrared space-born facilities (ISO, Spitzer and Herschel) have each pushed the frontiers, helping us to uncover the complex processes which govern the formation of stars and planets. The unique capabilities of the James Webb Space Telescope (JWST) now allow us to study the, otherwise inaccessible, processes governing the formation of stars and planets, to an unprecedented detail. As a space-based cryogenic 6.5m telescope, JWST represents a staggering improvement in sensitivity along with unprecedented spatial resolution across the near and mid-infrared.

The first full year of operations will be filled with revolutionary discoveries. This session will focus on the first results from JWST after the first year of operations, in the context of the star and planet formation, from PDRs to planets. This meeting provides the perfect opportunity to discuss the experiences scientists have accumulated over this first year regarding observing strategies and the interpretation and modeling of JWST data. This symposium aims to strengthen the links between these communities and establish, early on in the mission lifetime, the key science drivers for follow-up studies.
