The binary star Algol is one of the most famous eclipsing binary stars in our night sky. Algol is useful because of its clockwork dimming every 2.87 days. This creates a frequent opportunity collect data using UBVRI filters during the primary eclipse, secondary eclipse, and non-eclipsing phases. Using the blackbody formula, a theoretical model of the number of counts for each filter and phase was created. When compared with the observed number of counts for each phase, I was able to calculate a unique temperature and radius for the two stars.
