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…

Three-step growth of vapor-deposited ice under mesospheric temperature and water vapor conditions

Reo Sato, Kentaro Noguchi, Hiroyuki Koshida +2

Polar mesospheric clouds provide clues to physicochemical processes in the mesosphere and lower thermosphere. However, the heterogeneous nucleation and growth processes of water ic…

Hydrogenation of HOCO and formation of interstellar CO: A not so straightforward relation

Germán Molpeceres, Joan Enrique-Romero, Atsuki Ishibashi +5

Carbon dioxide (CO) is one of the most important interstellar molecules. While it is considered that it forms on the surface of interstellar dust grains, the exact contribution…

Proposed importance of HOCO chemistry: Inefficient formation of CO from CO and OH reactions on ice dust

Atsuki Ishibashi, Germán Molpeceres, Hiroshi Hidaka +3

With the advent of JWST ice observations, dedicated studies on the formation reactions of detected molecules are becoming increasingly important. One of the most interesting molecu…

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…

Methanol formation through reaction of low energy ions with an amorphous solid water surface at low temperature

Y. Nakai, W. M. C. Sameera, K. Furuya +3

We have performed experimental investigations of methanol formation via the reactions of low energy ions with an amorphous solid water (ASW) surface around 10 K. A new…
