Epsilon Aurigae (epsilon Aur) is a visually bright, eclipsing binary star system with a period of 27.1 years. The cause of each 18-month-long eclipse has been a subject of controversy for nearly 190 years because the companion has hitherto been undetectable. The orbital elements imply that the opaque object has roughly the same mass as the visible(More)
We report on a total of 106 nights of optical interferometric observations of the ò Aurigae system taken during the last 14 years by four beam combiners at three different interferometric facilities. This long sequence of data provides an ideal assessment of the system prior to, during, and after the recent 2009 2011 eclipse. We have reconstructed(More)

Astrophysical objects with unusually high mass to luminosity ratios attract attention. The fifth brightest star in the constellation Auriga, Aurigae, is such a case. The companion in this(More)
