Description:
    Eta Orionis (HD35411) is a multiple system which consists of at least
    four early B-type stars. In the present paper we focus on the
    double-lined spectroscopic eclipsing pair Aab, and in particular on
    component Ab, which is a remarkable intrinsically variable star. The
    presence of this variable in an eclipsing system enables us to
    determine accurately its mass, radius, inclination angle and rotation
    period.
