Collapse of turbulent massive cores with ambipolar diffusion and hybrid radiative transfer

(Abridged) Most massive protostars exhibit bipolar outflows. Nonetheless, there is no consensus regarding the mechanism at origin of these outflows, nor on cause less-frequently observed monopolar We aim to identify early protostellar focusing combined effects radiative transfer and magnetic fields in a turbulent medium. use four state-of-the-art radiation-magnetohydrodynamical simulations following collapse 100 Msun pre-stellar cores with Ramses code. Turbulence taken into account via initial velocity dispersion. hybrid method include ambipolar diffusion. find that turbulence delays launching which appear be mainly driven by magnetohydrodynamical processes. Magnetic tower flow magneto-centrifugal acceleration contribute former operates larger volumes than latter. Our finest resolution, 5 AU, does not allow us get converged results magneto-centrifugally accelerated Radiative takes place as well, dominates star vicinity, enlarges outflow extent, has negative impact outflows (up M~17 Msun, L~1e5 Lsun). The associated opening angles (20-30 deg when dominate) suggest additional (de-)collimating meet observational constraints. Outflows are launched nearly perpendicular disk misaligned core-scale fields, agreement several studies. In most run, monopolar. conclude processes dominate up ~17 against perturbs possible explanation for
