Gas phase Elemental abundances in Molecular cloudS (GEMS) XII. First look into the para-to-ortho ratio of c-C3D2 towards prestellar cores
J. Ferrer Asensio, A. Fuente, E. Roueff +3
Symmetric molecules with identical nuclei form distinct nuclear spin isomers (ortho and para) that cannot interconvert via radiative or inelastic transitions, preserving clues abou…
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…
Atom Addition Formation of Thionylimide (HNSO) on Interstellar Dust Grains: Chemical routes requiring oxygen and nitrogen atom surface diffusion
Juan Carlos del Valle, Miguel Sanz-Novo, Johannes Kästner +4
We investigate the formation of the recently detected HNSO molecule using quantum chemical calculations on ices and astrochemical models in tandem. Our results indicate that HNSO i…
Time-dependent chemical evolution during cloud formation: H-regulated chemistry in diffuse molecular cloud
Yuto Komichi, Yuri Aikawa, Kazunari Iwasaki +1
We investigate the chemical evolution of a forming molecular cloud behind an interstellar shock wave. We conduct three-dimensional magnetohydrodynamics simulations of the convergin…
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…
Extended and Compact Ortho-HD Structures Close to the Moment of Star-Formation: Evidence from ALMA-ACA Observations in Taurus
Kazuki Tokuda, Kenji Furuya, Naofumi Fukaya +8
Observing and characterizing pre- and protostellar cores in the earliest and densest stages of star formation is challenging due to their short timescales and high densities, limit…
