From Prestellar to Protostellar Cores II. Time Dependence and Deuterium Fractionation
Yuri Aikawa, Valentine Wakelam, Franck Hersant +2
We investigate the molecular evolution and D/H abundance ratios that develop as star formation proceeds from a dense-cloud core to a protostellar core, by solving a gas-grain react…
Polysulfanes on interstellar grains as a possible reservoir of interstellar sulphur
C. Druard, V. Wakelam
The form of depleted sulphur in dense clouds is still unknown. Until now, only two molecules, OCS and SO2, have been detected in interstellar ices but cannot account for the elemen…
CID: Chemistry In Disks VII. First detection of HC3N in protoplanetary disks
E. Chapillon, A. Dutrey, S. Guilloteau +8
Molecular line emission from protoplanetary disks is a powerful tool to constrain their physical and chemical structure. Nevertheless, only a few molecules have been detected in di…
Chemistry in the First Hydrostatic Core Stage By Adopting Three-Dimensional Radiation Hydrodynamic Simulations
Kenji Furuya, Yuri Aikawa, Kengo Tomida +5
We investigate molecular evolution from a molecular cloud core to a first hydrostatic core in three spatial dimensions. We perform a radiation hydrodynamic simulation in order to t…
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…
A KInetic Database for Astrochemistry (KIDA)
V. Wakelam, E. Herbst, J. -C. Loison +31
We present a novel chemical database for gas-phase astrochemistry. Named the KInetic Database for Astrochemistry (KIDA), this database consists of gas-phase reactions with rate coe…
