Description
In this work we investigate the early stages of the formation of disks around protostars. We present 2D axially symmetric MHD simulations of the collapse of a rotating molecular cloud with an initial density distribution following a Bonnor-Ebert-sphere into the 1st and 2nd hydrostatic Larson core. We perform a parameter study for a range of initial cloud masses and aim to simulate the first few thousand years of disk evolution, includinmg the launching, acceleration, collimation and initial propagation of the jet. The remnants of the first core collapsing into the second core form a Keplerian disk, which is flattened quickly by angular momentum and grows outwards over time due to the travelling shock front, reaching an extent of over 100 AU.
