Algol Animation With Graph
his is an animation of Algol showing how the light from the system varies as a function of the
orbit. Check the graph at the top right. There is a slight reduction of light when the bigger but
dimmer star (yellow) is behind the blue one, and a much deeper dip when the blue star is obscured.
Algol, or Beta Persei,l is the prototype of an entire class of eclipsing binary stars called Algol
systems. You can see a similar animation here
