The pyRate model requires nondiffusive chemistry to form observed S-bearing species in irradiated CO2:CS2 ice but overpredicts OCS, CS and SO while underpredicting SO2 and sulfur allotropes.
ALMA survey detects hot corino chemistry in 3/5 Class 0/I protostars with CH3OH column densities 10^17-10^18 cm^{-2} and rotational temperatures 200-250 K, showing two orders of magnitude variation in COM ratios.
