Purchase includes a free trial membership in the publisher's book club where you can select from more than a million books without charge. Excerpt: Epsilon Aurigae ( Aur / Aurigae) is a star in the constellation Auriga. It is traditionally known as Almaaz, Haldus, or Al Anz. Epsilon Aurigae is an eclipsing binary system composed of a Fo supergiant and a companion which is generally accepted to be a huge dark disk orbiting an unknown object, possibly a binary system of 2 small B-type stars. This star is special because the large supergiant is being elipsed by something even bigger and beause this object is almost completely dark, instead of an expected supergiant star. About every 27 years, epsilon Aurigae's brightness drops from an apparent visual magnitude of +2.92 to +3.83 . This dimming lasts between 640-730 days . In addition to this eclipse, the system also has a low amplitude pulsation with a period around 66 days. The system lies approximately 2,000 light years from Earth. Epsilon Aurigae was first suspected to be a varia...More: http: //booksllc.net/?id=2101873
