Sulfur Ice Astrochemistry: A Review of Laboratory Studies

Abstract Sulfur is the tenth most abundant element in universe and known to play a significant role biological systems. Accordingly, recent years there has been increased interest of sulfur astrochemical reactions planetary geology geochemistry. Among many avenues research currently being explored laboratory processing astrophysical ice analogues. Such involves synthesis an specific morphology chemical composition at temperatures pressures relevant selected setting (such as interstellar medium or surfaces icy moons). Subsequent under conditions that simulate commonly radiolysis, photolysis, thermal processing, neutral-neutral fragment chemistry, any combination these, subject several studies. The in-situ changes chemistry occurring during such are often monitored via spectroscopic spectrometric techniques. In this paper, we have reviewed results investigations concerned with Specifically, review (i) spectroscopy sulfur-containing molecules condensed phase, (ii) atom radical addition reactions, (iii) sulfur-bearing ices, (iv) photochemical experiments, (v) non-reactive charged particle radiolysis (vi) ion bombardment implantation Potential future studies field solid phase astrochemistry also discussed context forthcoming space missions, NASA James Webb Space Telescope ESA Jupiter Icy Moons Explorer mission.
