Resetting chemical clocks of hot cores based on S-bearing molecules
Valentine Wakelam, Paola Caselli, Cecilia Ceccarelli +2
We report a theoretical study of sulphur chemistry, as applied to hot cores, where S-bearing molecular ratios have been previously proposed and used as chemical clocks. As in previ…
