Abstract

During star formation, both infall of gas towards the protostar and outflows (jets ans molecular outflows) are present around class 0 and 1 young stellar objects (YSOs). Here, we present a self-similar model describing accretion and bipolar molecular outflows from one single set of equations. The gas composition directly influences the solutions. Indeed, the density in the equatorial region is inversely increasing with metallicity. This gives rise to large accretion rates onto massive protostars, such as primordial stars. We also show preliminary numerical simulations of YSO jets.
