Binary star light curve
WebAug 3, 2024 · A light curve is a graph of brightness vs. time. The light curve shown here was made from brightness data gathered by the Kepler Mission for discovery of planet Kepler-20c. Light curves of some objects are periodic: eclipsing binary stars, certain other variable stars, and of special interest to Kepler & K2 scientists, transiting extrasolar ...

Exercise 1: Binary Stars - investigate a spectroscopic binary system; Binary stars are of great importance to astronomers as they provide … WebWe derived the binary mass ratio M G /M B = 0.17 ± 0.03 based on the assumption that the G-type secondary fills its Roche lobe and rotates synchronously. Using this value of the mass ratio as well as the radial velocities of the G-star, we obtained a consistent light curve model and improved estimates of the stellar masses, radii, luminosities ...
