Eclipsing binary star definition
WebSep 14, 2024 · The eclipsing-binary method uses the idea that a star's luminosity can be defined as L = 4 π f s R 2, where f s is the flux per unit area from the star's surface and R is the radius of the star. So how do we determine those? WebMay 7, 2015 · A light curve is a graph which shows the brightness of an object over a period of time. In the study of objects which change their brightness over time such as novae, supernovae, and variable stars, the light curve is a simple, but valuable tool to a scientist.
