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…
Gas phase Elemental abundances in Molecular cloudS (GEMS). X. Observational effects of turbulence on the chemistry of molecular clouds
L. Beitia-Antero, A. Fuente, D. Navarro-Almaida +12
(Abridged) We explore the chemistry of the most abundant C, O, S, and N bearing species in molecular clouds, in the context of the IRAM 30 m Large Programme Gas phase Elemental abu…
The 2024 KIDA network for interstellar chemistry
V. Wakelam, P. Gratier, J. -C. Loison +3
The study of the chemical composition of the interstellar medium (ISM) requires a strong synergy between laboratory astrophysics, modeling, and observations. In particular, astroch…
A fast neural emulator for interstellar chemistry
A. Asensio Ramos, C. Westendorp Plaza, D. Navarro-Almaida +3
Astrochemical models are important tools to interpret observations of molecular and atomic species in different environments. However, these models are time-consuming, precluding a…
Grain growth and its chemical impact in the first hydrostatic core phase
D. Navarro-Almaida, U. Lebreuilly, P. Hennebelle +8
The first hydrostatic core (FHSC) phase is a brief stage in the protostellar evolution that is difficult to detect. Our goal is to characterize the chemical evolution of gas and du…
A New Reference Chemical Composition for TMC-1
P. Gratier, L. Majumdar, M. Ohishi +4
Recent detections of complex organic molecules in dark clouds have rekindled interest in the astrochemical modeling of these environments. Because of its relative closeness and ric…
