- Abstract
We have studied the effect of the gas accretion flow on the distribution of molecules in hot inner regions of young circumstellar disks. The gas-phase reactions initiated by evaporation of icy mantle on dust grains are calculated along the accretion flow, and the molecular line emission is simulated using the obtained abundance profiles. Our results have shown that some evaporated molecules keep high abundances and emit strong transition lines only when the accretion velocity is high enough.
