The KInetic Database for Astrochemistry (KIDA)
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 coefficients andExpand
The Cologne Database for Molecular Spectroscopy, CDMS, in the Virtual Atomic and Molecular Data Centre, VAMDC
Abstract The Cologne Database for Molecular Spectroscopy, CDMS, was founded 1998 to provide in its catalog section line lists of mostly molecular species which are or may be observed in variousExpand
Desorption rates and sticking coefficients for CO and N2 interstellar ices
We present Temperature Programmed Desorption (TPD) experiments of CO and N2 ices in pure, layered and mixed morphologies at various ice "thicknesses" and abundance ratios as well as simultaneouslyExpand
H3(+) + H2 isotopic system at low temperatures: microcanonical model and experimental study.
State-to-state thermal rate coefficients for reactions of all H(3)(+) + H(2) isotopic variants are derived and compared to new experimental data and shown to be consistent with the detailed balance and thermodynamical equilibrium constants. Expand
Competition between CO and N-2 desorption from interstellar ices
Millimeter observations of pre- and protostellar cores show that the abundances of the gas-phase tracer molecules, C 18 O and N2H, anticorrelate with each other and often exhibit “holes” where theExpand
Chemical models used to study the chemical composition of the gas and the ices in the interstellar medium are based on a network of chemical reactions and associated rate coefficients. These reactiExpand
At the high densities and low temperatures found in star forming regions, all molecules other than H2 should stick on dust grains on timescales shorter than the cloud lifetimes. Yet these clouds areExpand
Interstellar OH+, H2O+ and H3O+ along the sight-line to G10.6–0.4
We report the detection of absorption lines by the reactive ions OH + ,H 2O + and H3O + along the line of sight to the submillimeter continuum source G10.6−0.4 (W31C). We used the Herschel HIFIExpand
Rotational spectroscopy of the isotopic species of silicon monosulfide, SiS.
An improved set of spectroscopic parameters for SiS has been derived which include several terms describing the breakdown of the Born-Oppenheimer approximation, and highly accurate rotational frequencies for this important astronomical molecule can now be predicted well into the terahertz region.

Herschel/HIFI observations of interstellar OH+ and H2O+ towards W49N: a probe of diffuse clouds with a small molecular fraction
We report the detection of absorption by interstellar hydroxyl cations and water cations, along the sight-line to the bright continuum source W49N. We have used Herschel's HIFI instrument, in dualExpand
