KROME - a package to embed chemistry in astrophysical simulations
T. Grassi, S. Bovino, D. R. G. Schleicher +4
Chemistry plays a key role in many astrophysical situations regulating the cooling and the thermal properties of the gas, which are relevant during gravitational collapse, the evol…
CH+ depletion by atomic hydrogen: accuracy of new rates in photo-dominated and self-shielded environments
S. Bovino, T. Grassi, M. Tacconi +1
A detailed quantum analysis of a ionic reaction with a crucial role in the ISM is carried out to generate ab initio reactive cross sections with a quantum method. From them we obta…
Carbon Cations and Silicon Atoms in the ISM: modeling their charge exchange reaction
M. Satta, T. Grassi, F. A. Gianturco
The time-dependent rate coefficients for the charge exchange reaction C+ + Si -> C + Si+ for doublet and quartet states have been determined with ab initio quantum calculations cou…
Chemical complexity in astrophysical simulations: optimization and reduction techniques
T. Grassi, S. Bovino, D. Schleicher +1
Chemistry has a key role in the evolution of the interstellar medium (ISM), so it is highly desirable to follow its evolution in numerical simulations. However, it may easily domin…
Electron attachment rates for PAH anions in the ISM and dark molecular clouds: dependence on their chemical properties
F. Carelli, T. Grassi, F. A. Gianturco
CONTEXT: The attachment of free electrons to polycondensed aromatic ring molecules (PAHs) is studied for the variety of these molecules with different numbers of condensed rings an…
Electron-attachment rates for carbon-rich molecules in protoplanetary atmospheres: the role of chemical differences
F. Carelli, T. Grassi, F. Sebastianelli +1
The formation of anionic species in the interstellar medium from interaction of linear molecules containing carbon, nitrogen and hydrogen as atomic components (polyynes) with free…
