SILCC-Zoom: the dynamic and chemical evolution of molecular clouds

Popis výsledku v původním jazyce

We present 3D 'zoom-in' simulations of the formation of two molecular clouds out of the galactic interstellar medium. We model the clouds-identified from the SILCC simulations with a resolution of up to 0.06 pc using adaptive mesh refinement in combination with a chemical network to follow heating, cooling and the formation of H-2 and CO including (self-) shielding. The two clouds are assembled within a few million years with mass growth rates of up to similar to 10(-2) M-circle dot yr(-1) and final masses of similar to 50 000 M-circle dot. A spatial resolution of less than or similar to 0.1 pc is required for convergence with respect to the mass, velocity dispersion and chemical abundances of the clouds, although these properties also depend on the cloud definition such as based on density thresholds, H-2 or CO mass fraction.
