Astrochemistry

A key question for the study of planet atmospheres is to understand how much of the molecular complexity develops during the formation of stars and is available in the disks for delivery on the pristine planet surfaces. The main goal is to obtain the chemical content of the disk-jet systems of the earliest stages of Sun-like star forming regions. The chemistry of shocks is investigated, either fast shocks driven by jets or slow shocks associated with infalling motions on accretion disks. Thanks to the involvement in the ALMA FAUST LP we obtain proxies of protoplanetary disks and interpret them via astrochemical models. The goals are to obtain radial profile of the gas temperature and density in the disk, to image the molecular complexity and abundances in disks and to compare key molecular abundance ratios with those derived for protoplanetary disks and Solar System objects.
