Scientific paper

Polarization and light curves of the recent eclipse of ɛ Aur are presented and modeled, using a tilted, opaque secondary disk and a model atmosphere for the F Ia primary star. That model qualitatively explains the striking asymmetries in the observed curves. But out-of-eclipse polarimetry shows the primary to be a nonradial pulsator, and this will have to be included in a truly quantitative picture of the eclipse and the system.
