Colloquium: A new window into planet formation with JWST

Prof. Inga Kamp (Kapteyn Institute, Groningen, NL) will show us the latest JWST observations of planet-forming disks and discuss their constraints for planet formation.

Our understanding of planet formation has changed recently, embracing the new idea of pebble accretion. This means that the influx of pebbles from the outer regions of planet-forming disks to their inner zones together with diffusion and collisional mixing processes could influence the composition of the building blocks of planets. This could then further propagate into the composition of planets and their atmospheres. The solid and molecular components delivered to the planet-forming region can be best characterized by mid-infrared spectroscopy. Due do the sensitivity and spectral resolution provided by JWST we now have a unique tool to obtain the full inventory of chemistry in the inner disks of solar-types stars and brown dwarfs, including also less abundant hydrocarbons and isotopologues. In this talk, I will present the first results of the MINDS (MIRI mid-INfrared Disk Survey, PI: Th. Henning) survey, connect them to thermo-chemical disk models and discuss how this informs our understanding of transport and mixing processes in young planet forming disks.
