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…
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…
Methane Formation Efficiency on Icy Grains: Role of Adsorption States
Masashi Tsuge, Germán Molpeceres, Yuri Aikawa +1
Methane (CH4) is one of the major components of the icy mantle of cosmic dust prevalent in cold, dense regions of interstellar media, playing an important role in the synthesis of…
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…
Coverage Dependent H Desorption Energy: a Quantitative Explanation Based on Encounter Desorption Mechanism
Qingkuan Meng, Qiang Chang, Gang Zhao +5
Recent experiments show that the desorption energy of H on a diamond-like carbon (DLC) surface depends on the H coverage of the surface. We aim to quantitatively explain th…
