The 10 pages that link to Eclipsing binary, each with the reason it gives.
Light curveBroader topic: Its alternating eclipses produce repeating light-curve minima.
Stellar radiusRelated: Eclipse timing and light curves can yield precise stellar radii.
AlgolNarrower topic: Mutual eclipses of Algol’s inner pair cause its prominent brightness dips.
Flare starCompared with: Its dips arise from orbital geometry, not magnetic energy release.
