The origin of chemical complexity: in the earth of young forming planetary system

Early planetary system formation reveals intricate chemistry with abundant prebiotic molecules in protostellar environments that serves as a crucial diagnostic tool for understanding underlying physical processes. Protostellar systems, at high angular resolution (below 100 au), exhibit complex interconnected physical processes, expanding beyond the traditional model of accreting central objects ejecting powerful jets to include compact disks, accretion streamers, shocks, and disk winds. The interplay between accretion and ejection mechanisms has a key role in the distribution of gas and dust in the disk, influencing the chemical content inherited by forming planets.
