Disk formation with ambipolar diffusion from low- to high-mass star formation

I will present the results of 3D protostellar collapse calculations of a wide range of initial mass (from 0.5 to 100 solar mass). The calculations are performed using the RAMSES code, including the effect of non-ideal MHD with the ambipolar diffusion and radiative transfer. I will show how ambipolar diffusion is regulating the disk and outflow formation. I will discuss the disk properties: magnetisation level, magnetic field lines topology, stability. I will finally present preliminary results of protostellar collapse models which includes dust dynamics.
