The absence of sufficiently efficient braking mechanisms for newly formed stars points to the star formation process itself as the origin. I find that a mode of star formation exists by which a protostar can form without accreting angular momentum. It depends on the survival of a magnetic connection between the accreting matter and the birth cloud. The conditions for this process to operate are analyzed, and illustrated with a generic (scale-free) model.
