from AE Aquarii

Abstract.
The reported nightly mean value of the circular
polarization of optical emission observed from the close binary
system AE Aqr is 0.06% +/- 0.01%. We discuss a possibility that
the observed polarized radiation is emitted mainly by the white
dwarf or its vicinity. We demonstrate that this hypothesis is
rather unlikely since the contribution of the white dwarf to the
optical radiation of the system is too small. This indicates that
the polarimetric data on AE Aqr cannot be used for the evaluation of
the surface magnetic field strength of the white dwarf in this
system.
