In astronomy, a light curve is a graph of the light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y-axis and with time on the x-axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid varia… WebThe DEPTH of the two eclipses in a light curve is one way to find out when the hotter star is being blocked, and when the cooler star is being blocked. But there's another method we can use, too. Q: Suppose we measure the combined color of the light from both stars. During each eclipse, how does the color of the system change? My answer.
