Abstract

We report the detection of modulated circular polarization in V795 Her. The degree of polarization increases with wavelength and is modulated with a period of 19.54 min, which is very close to the reported optical QPO period. The modulation has a peak-to-peak amplitude of 0.12% in the U-band. The estimated magnetic field intensity is in the range 2--7 MG.
