Molecule-specific diffusion and desorption of interstellar ices on carbonaceous dust
Yi-Hsuan Chiu, Tushar Suhasaria, Cornelia Jäger +4
Interstellar ices form on dust grains in the coldest regions of molecular clouds and preserve key volatile reservoirs that could be incorporated into protoplanetary disks during st…

Experimental investigation of O2 diffusion and entrapment in interstellar amorphous solid water (ASW)
Lina Coulaud, Julia C. Santos, Ko-Ju Chuang
Interstellar ices are mainly composed of amorphous solid water (ASW) containing small amounts of hypervolatiles, such as O2, whose diffusion-limited reactions play a key role in sp…

Interaction of HS with H atoms on grain surfaces under molecular cloud conditions
Julia C. Santos, Harold Linnartz, Ko-Ju Chuang
Hydrogen sulfide (HS) is thought to be efficiently formed on grain surfaces through the successive hydrogenation of S atoms. Its non-detection so far in astronomical observatio…
