This applet demonstrates how one can infer the diameters and temperature of stars by measuring the brightness variations seen in an eclipsing binary star system. The applet displays binary stars eclipsing each other. The user can control the photospheric temperature and radius of each star, as well as the orbital radius and inclination. The applet also allows the user to simulate the effect of noisy data by setting the random error of measurement as a fraction of the total brightness of both stars. The simulation will continue to calculate the system brightness, averaging its results with the previous trials.
This is part of a larger collection of applets by STEM Colorado focused mostly on topics in astronomy.
