The Dense Gas Fraction in Galactic Center Clouds
E. A. C. Mills, A. Ginsburg, K. Immer +5
We present an analysis of gas densities in the central R=300 parsecs of the Milky Way, focusing on three clouds: GCM-0.02-0.07 (the 50 km/s cloud), GCM-0.13-0.08 (the 20 km/s cloud…
Collisional Excitation and Weak Maser Action of Interstellar Methanimine
Alexandre Faure, François Lique, Anthony J. Remijan
The inelastic cross sections and rate coefficients for the rotational excitation of methanimine (CHNH) by cold H have been determined quantum mechanically based on a new hi…
Modelling the molecular composition and nuclear-spin chemistry of collapsing prestellar sources
P. Hily-Blant, A. Faure, C. Rist +2
We study the gravitational collapse of prestellar sources and the associated evolution of their chemical composition. We use the University of Grenoble Alpes Astrochemical Network…
Abundance of HCN and its C and N isotopologues in L1498
Victor S. Magalhaes, Pierre Hily-Blant, Alexandre Faure +2
The isotopic ratio of nitrogen in nearby protoplanetary disks, recently measured in CN and HCN, indicates that a fractionated reservoir of nitrogen is available at the stage of com…
Electron-impact excitation of diatomic hydride cations II: OH and SH
James R Hamilton, Alexandre Faure, Jonathan Tennyson
R-matrix calculations combined with the adiabatic-nuclei-rotation and Coulomb-Born approximations are used to compute electron-impact rotational rate coefficients for two open-shel…
An efficient statistical method to compute molecular collisional rate coefficients
Jérôme Loreau, François Lique, Alexandre Faure
Our knowledge about the "cold" Universe often relies on molecular spectra. A general property of such spectra is that the energy level populations are rarely at local thermodynamic…
