To test his speculations, he needed data on the masses of stars, potentially available from eclipsing binary stars.
The properties of stars derived from eclipsing binary systems are not necessarily applicable to isolated single stars.
Other variables include eclipsing binary stars (both Algol type and contact binaries), flare stars, and spectrum variables, such as Pleione.
Observations of the eclipsing binary 31 Cygni show that the K-type supergiant component has an extremely inhomogeneous, extended atmosphere composed of numerous blobs and filaments.
Radii are found from eclipsing binary systems, from direct measurements in a few favourable cases, by calculations, and from absolute visual magnitudes and temperatures.
Beta Lyrae, eclipsing binary star, the two component stars of which are so close together that they are greatly distorted by their mutual attraction; they exchange material and share a common atmosphere.
One of the nearest stars in Caelum is the eclipsing binary star RR Caeli, at a distance of 20.13 pc.
I'm in charge of detecting circumbinary planets that orbit eclipsing binary stars -- planets that orbit around both stars while the two stars orbit around each other.
South of the Eagle Nebula on the border with Sagittarius is the eclipsing binary W Serpentis, whose primary is a white giant that is interacting with the secondary.
Two years later Stebbins used the photometer and discovered four stars to be eclipsing binary stars: Beta Aurigae, Spica, Alpha Coronae Borealis and Delta Orionis.
