Effect of Ice Charging on the Astrochemistry of Interstellar Sulfur Bearing Species on Amorphous Solid Water
The episode discusses a paper analyzing how an excess negative charge on interstellar ice affects sulfur-bearing species. The authors propose that treating ice as a charged, active surface—rather than a neutral one—significantly increases the binding energy of molecules like ext SO 2. This suggests that much of the missing sulfur may be trapped in these solid phases, requiring major revisions to current chemical models.
