Mass Transfer in the Binary Star Algol

This site shows the dynamic hydrodynamic models have shown that the circumstellar flow in Algol is relatively independent of the initial speed and direction of the tidal stream. Rather, the flow dynamics are determined primarily by the strength of radiative cooling, which depends on the density of the gas in the mass transfer stream.
