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 ( . ...

... Impedance . Electrical impedance, or simply impedance, describes a measure of opposition to a sinusoidal alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. ... Resistance is the real part of impedance; a device with a purely resistive impedance exhibits no phase shift between the voltage and current. ...
