Time-dependent chemical evolution during cloud formation: H $_{2}$ -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…

Extended and Compact Ortho-H $_{2}$ D $^{+}$ 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…

Digging into the Interior of Hot Cores with ALMA (DIHCA). V. Deuterium Fractionation of Methanol

Takeshi Sakai, Nobuhito Shiomura, Patricio Sanhueza +16

We have observed the $^{13}$ CH $_{3}$ OH $5_{1} - 4_{1}$ A $^{+}$ , $^{13}$ CH $_{3}$ OH $1 4_{1} - 1 3_{2}$ A $^{-}$ , and CH $_{2}$ DOH $8_{2, 6} - 8_{1, 7}$ $e_{0}$ lines toward 24 high-mass star-forming regions by usi…

Chemical Evolution during Molecular Cloud Formation Triggered by an Interstellar Shock Wave: Dependence on Shock Parameters and Comparison with Molecular Absorption Lines

Yuto Komichi, Yuri Aikawa, Kazunari Iwasaki +1

We investigate chemistry in the compression layer behind the interstellar shock waves, where molecular cloud formation starts. We perform three-dimensional magnetohydrodynamics sim…
