SILCC-Zoom: The early impact of ionizing radiation on forming molecular clouds
Original language description
We present our first sub-parsec resolution radiation hydrodynamic simulations of two molecular clouds self-consistently forming from a turbulent, multiphase ISM. The clouds have similar initial masses of few 10(4) M-circle dot, escape velocities of -5 km s(-1), and a similar initial energy budget. We follow the formation of star clusters with a sink-based model and the impact of radiation from individual massive stars with the tree-based radiation transfer module TREERAY. Photoionizing radiation is coupled to a chemical network to follow gas heating, cooling, and molecule formation and dissociation. For the first 3 Myr of cloud evolution, we find that the overall star formation efficiency is considerably reduced by a factor of similar to 4 to global cloud values of < 10 per cent as the mass accretion of sinks that host massive stars is terminated after less than or similar to 1 Myr. Despite the low efficiency, star formation is triggered across the clouds.
