H Ortho-Para Spin Conversion on Inhomogeneous Grain Surfaces. II. impact of the rotational energy difference between adsorbed ortho-H and para-H and implication to deuterium fractionation chemistry
Kenji Furuya, Toshiki Sugimoto, Kazunari Iwasaki +2
We investigate how the H ortho-to-para ratio (OPR) and dueterium fractionation in star-forming regions are affected by nuclear spin conversion (NSC) on dust grains. Particular…
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…
Molecular Mobility of Extraterrestrial Ices: Surface Diffusion in Astrochemistry and Planetary Science
N. F. W. Ligterink, C. Walsh, H. M. Cuppen +12
Molecules are ubiquitous in space. They are necessary component in the creation of habitable planetary systems and can provide the basic building blocks of life. Solid-state proces…
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…
