Light curve - Wikipedia
WebThe light curve of an eclipsing binary—i.e., a plot of its changes in brightness over time—has a deep minimum when the brighter star is eclipsed and a shallower minimum when the dimmer star is eclipsed. The variable star Algol, or Beta Persei, was the first eclipsing binary to be recognized as such. Eclipsing binaries are the principal ... WebThe effects of light refraction in eclipsing binary systems were calculated by Kudzei [8]. These effects should result in small humps (brightenings) in the light curve before and after the eclipse, as well as in the middle of the eclipse. Since there are no such humps in the light curves of HD 189733, refraction effects in these light curves can Web11 nov. 2024 · He suggests the ancient Egyptians had noted Algol’s changes in brightness, which can be seen with the naked eye.
