Context. Due to the presence of magnetic fields, protostellar jets/outflowsare a natural consequence of accretion onto protostars. They are expected toplay an important role for star and protoplanetary disk formation. Aims. We aimto determine the influence of outflows on star and protoplanetary diskformation in star forming clumps. Methods. Using RAMSES, we perform the firstmagnetohydrodynamics calculation of massive star-forming clumps with ambipolardiffusion, radiative transfer including the radiative feedback of protostarsand protostellar outflows while systematically resolving the disk scales. Wecompare it to a model without outflows. Results. We find that protostellaroutflows have a significant impact on both star and disk formation. Theyprovide significant additional kinetic energy to the clump, with typicalvelocities of a few 10 km/s, impact the clump and disk temperatures, reduce theaccretion rate onto the protostars and enhance fragmentation in the filaments.We find that they promote a more numerous stellar population. They do notimpact much the low mass end of the IMF, which is probably controlled by themass of the first Larson core, however, that they have an influence on its peakand high-mass end. Conclusions. Protostellar outflows appear to have asignificant influence on both star and disk formation and should therefore beincluded in realistic simulations of star-forming environments.
