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…

H2S ice sublimation dynamics: experimentally constrained binding energies, entrapment efficiencies, and snowlines
Julia C. Santos, Elettra L. Piacentino, Jennifer B. Bergner +2
Hydrogen sulfide (H2S) is thought to be an important sulfur reservoir in interstellar ices. It serves as a key precursor to complex sulfur-bearing organics, and has been proposed t…
