Star formation and feedback: a subparsec-resolution simulation of the Milky-Way

The properties of the ISM and the structure of molecular clouds are set by the turbulence cascade from up to galactic scale. Star forming clumps are then altered by the feedback from massive stars, which regulates their fragmentation by adding a thermal and pressure support. We present a new adaptive mesh refinement (AMR) simulation of the Milky-Way which provides self-consistent initial conditions for star formation in GMCs, and even resolves their main substructures down to scales of 0.05pc in the full, self-consistent galactic context. A realistic description of the stellar feedbacks through photo-ionization, radiative pressure and supernova explosions is included. By resolving the spacial structures over almost 6 decades in space and 10 decades in density, we are able to monitor precisely the evolution of molecular clouds and the formation of stars.
