eclipsing binary

(binary star system detected by variations in magnitude)

An eclipsing binary is a binary star system in which one star passes in front of the other, detected by the reduction in observed light when that occurs, much as a transiting planet is detected. It is a type of variable star, with a variable type of E. It is one of a number binary-star classes based upon how the star is determined to be binary. Others:

A double-line detached eclipsing binary (DDEB) is an eclipsing binary that is also a double-line spectroscopic binary and a detached binary (not in contact).
