Testing various assumptions for radiolysis, non-diffusive chemistry, and chemical desorption in cold cores
V. Wakelam, T. Tu
To study interstellar gas and grain chemistry, gas-phase astrochemical models have been developed since the early 1980s and gas-grain models since the 1990s. Each published model i…
Ice chemistry that can be unveiled with the JWST: SynthIceSpec, a synthetic spectrum generator to test spectral limits. Solid CO_2 as a dust thermometer and solid CH_3CN detectability in cold cores
A. Taillard, P. Gratier, J. A. Noble +7
As the (JWST) pursues its observing journey, several thousands of icy-grain spectra are expected to be measured and analysed. The inventory of ices in particular, via the observati…
Simulation of proton radiolysis of H2O and O2 ices with the Nautilus code
Tian-Yu Tu, Valentine Wakelam, Jean-Christophe Loison +3
The radiolysis effect of cosmic rays (CRs) plays an important role in the chemistry in molecular clouds. CRs can dissociate the molecules on dust grains, producing reactive suprath…
Chemical constraints on the dynamical evolution of the cold core L694
A. Taillard, V. Wakelam, P. Gratier +4
In star-forming regions, molecular cloud history and dynamics set the trend in the chemical composition. Ice formation, in particular, is affected by the evolution of physical cond…
