Water delivery from cores to disks: deuteration as a probe of the prestellar inheritance of H2O
K. Furuya, M. N. Drozdovskaya, R. Visser +5
We investigate the delivery of regular and deuterated forms of water from prestellar cores to circumstellar disks. We adopt a semi-analytical axisymmetric two-dimensional collapsin…
On the Inference of the Cosmic Ray Ionization Rate from the HCO-to-DCO Abundance Ratio: The Effect of Nuclear Spin
Christopher N. Shingledecker, Jennifer B. Bergner, Romane Le Gal +3
The chemistry of dense interstellar regions was analyzed using a time-dependent gas-grain astrochemical simulation and a new chemical network that incorporates deuterated chemistry…
Chemical and physical characterization of collapsing low-mass prestellar dense cores
U. Hincelin, B. Commercon, V. Wakelam +3
The first hydrostatic core, also called the first Larson core, is one of the first steps in low-mass star formation, as predicted by theory. With recent and future high performance…
Water deuteration and ortho-to-para nuclear spin ratio of H2 in molecular clouds formed via the accumulation of HI gas
K. Furuya, Y. Aikawa, U. Hincelin +4
We investigate the water deuteration ratio and ortho-to-para nuclear spin ratio of H2 (OPR(H2)) during the formation and early evolution of a molecular cloud, following the scenari…
Elemental nitrogen partitioning in dense interstellar clouds
Julien Daranlot, Ugo Hincelin, Astrid Bergeat +4
Many chemical models of dense interstellar clouds predict that the majority of gas-phase elemental nitrogen should be present as N2, with an abundance approximately five orders of…
