The presence of eclipses places Thuban into the class of binaries known as eclipsing binaries. She wrote numerous articles on eclipsing stars and other astronomical objects. Only Epsilon Aurigae has a longer period among eclipsing binaries. The Applegate mechanism explains long term orbital period variations seen in certain eclipsing binaries. An example of an eclipsing binary is Epsilon Aurigae in the constellation Auriga. Modern 8-meter-class optical telescopes have discovered eclipsing binaries throughout the Local Group. Algol gives its name to its class of eclipsing variable, known as Algol variables. By 1984, Stacey Swain was already eclipsing her bandmates in popularity. Epsilon Aurigae is the longest-period eclipsing binary currently known. It forms the prototype of a class of ellipsoidal "contact" eclipsing binaries. Examples of eclipsing binaries are Epsilon Aurigae, VV Cephei, and HR 5171. The result is a type of extrinsic variable star system called an eclipsing binary. KIC 9832227 is an example of an eclipsing contact binary star system. There are two main groups of extrinsic variables&colon; rotating stars and eclipsing stars. The final design chosen was a behemoth, eclipsing any large transport then built.
