Virtually all detailed gas-phase models of the chemistry of dense interstellar clouds exclude polycyclic aromatic hydrocarbons (PAHs). This omission is unfortunate because from the few studies thatExpand
Non-thermal desorption from interstellar dust grains via exothermic surface reactions
Aims. The gas-phase abundance of methanol in dark quiescent cores in the interstellar medium cannot be explained by gas-phase chemistry. In fact, the only possible synthesis of this species appearsExpand
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 Hot Core around the Low-Mass Protostar IRAS 16293–2422: Scoundrels Rule!
While warm dense gas is prevalent around low-mass protostars, the presence of complex saturated molecules—the chemical inventory characteristic of hot cores—has remained elusive in such environments.Expand
Gas and grain chemical composition in cold cores as predicted by the Nautilus three-phase model
We present an extended version of the 2-phase gas-grain code NAUTILUS to the 3-phase modelling of gas and grain chemistry of cold cores. In this model, both the mantle and the surface are consideredExpand
Molecular Evolution and Star Formation: From Prestellar Cores to Protostellar Cores
We investigate molecular evolution in a star-forming core that is initially a hydrostatic starless core and collapses to form a low-mass protostar. The results of a one-dimensionalExpand
TIMASSS: the IRAS 16293-2422 millimeter and submillimeter spectral survey. I. Observations, calibration, and analysis of the line kinematics
While unbiased surveys observable from ground-based telescopes have previously been obtained towards several high mass protostars, very little exists on low mass protostars. To fill up this gap, weExpand
Oxygen depletion in dense molecular clouds: a clue to a low O_2 abundance?
Context. Dark cloud chemical models usually predict large amounts of O2, often above observational limits. Aims. We investigate the reason for this discrepancy from a theoretical point of view,Expand
Chemistry in Disks. IV. Benchmarking gas-grain chemical models with surface reactions
Abridged: We detail and benchmark two sophisticated chemical models developed by the Heidelberg and Bordeaux astrochemistry groups. The main goal of this study is to elaborate on a few well-describedExpand
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
