Thermally irreversible sulfur chemisorption on silicate grains as a major sulfur reservoir in molecular clouds
Ni-En Sie, Masashi Tsuge, Yasuhiro Oba +3
Sulfur (S) chemistry in the interstellar medium remains poorly constrained due to the longstanding "missing sulfur" problem, where a significant fraction of cosmic sulfur in molecu…
Methanol Formation via the Radical-radical Reaction of OH and CH3 Radicals Undergoing Transient Diffusion on Ice at 10 to 60 K
Arisa Iguchi, Hiroshi Hidaka, Atsuki Ishibashi +3
Methanol (CH3OH) is thought to form on interstellar ice dust via successive hydrogenation reactions. The reaction between CH3 and OH radicals could also conceivably generate methan…
Formation of unsaturated carbon chains through carbon chemisorption on solid CO
Masashi Tsuge, Germán Molpeceres, Ryota Ichimura +3
The interaction of carbon atoms with solid carbon monoxide (CO) is a fundamental process in astrochemistry, influencing the formation of complex organic molecules in interstellar e…
Chemical pathways of SO2 with hydrogen atoms on interstellar ice analogues
Thanh Nguyen, Yasuhiro Oba, W. M. C. Sameera +2
Sulfur dioxide (SO2) is a sulfur-containing molecule expected to exist as a solid in the interstellar medium (ISM). In this study, we performed laboratory experiments and computati…
Photodesorption efficiency of OH radical on the ice surface in the wavelength range from ultraviolet to visible
Ni-En Sie, Masashi Tsuge, Yoichi Nakai +1
The photodesorption efficiencies of the hydroxyl (OH) radical from the water ice surface were measured in the range of 310-700 nm for the first time. Although isolated HO molec…
Determination of the branching ratio of CHOH + OH reaction on water ice surface at 10 K
Atsuki Ishibashi, Hiroshi Hidaka, W. M. C. Sameera +2
The CHO and CHOH radicals can be important precursors of complex organic molecules (COMs) in interstellar dust. The COMs presumably originating from these radicals were abu…
