Prairie Astronomy Club: Double Stars To Follow Part I by Martin Gaskell  Every amateur astronomer has heard of them. Every star atlas lists them. We've probably all glanced at a few of them. We know, in theory at least, that they orbit each other, but what about really following them as they...

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.
