Scientific paper

The low-mass model of Epsilon Aurigae consisting of an F supergiant star and a main-sequence B star which is surrounded by a cool accretion disc has been investigated. The disc requires a high accretion rate if one assumes the disc to be completely heated up by friction alone. One the other hand, discs with low accretion rates are possible when the disc are heated up from the radiation of both stars. A swollen crescent portion produced by the radiation of the F star may form a bulky body sufficient to obscure the radiation of the F star.
