Learning Goals: Students will learn how the changing light from an eclipsing binary star system can reveal information about the individual stars and their orbits.
Suggested Observations: Time-delay series of images of a known eclipsing binary star system timed during subsequent minima (the dimmest point in the lightcurve) e.g.: AB And, BU Vul, XZ And
Challenge: Find the period and relative luminosities of the components of an eclipsing binary star system. Observe an eclipsing binary and make a measurement of its period.
