UPPER PANEL: The gas surface density map in log scale. The red circle in the center represents the central protostar. The development of spiral structure in the protostellar disk is evident. Dense protostellar/protoplanetary clumsp form within the spiral arms and are driven into the protostar by the action of gravitational torques. LOWER PANEL: The mass accretion rate onto the protostar as a function of time. The mass accretion rate is characterized by very short ( . ...
