Discovery of the variable phase-locked polarization in LZ Cephei.


Abstract (from CDS):

The early-type non-eclipsing binary LZ Cep has been observed with the UBVRI polarimeter during 25 nights in 1996-1997. A variable phase-locked linear polarization has been found. The principal Fourier components of the observed variations are the second harmonics of the orbital period. The most probable explanation of this variability is reflection of the radiation from each component of the binary off the facing hemisphere of its companion. We have constructed a simple numerical model of the reflection process which is capable of reproducing the amplitude and phase dependence of the polarized light-curve.
