Abstract (from CDS):

We present time-resolved spectroscopy and circular spectropolarimetry of the SW Sex star RXJ1643.7+3402. We find significant polarization levels exhibiting a variability at a period of 19.38±0.39 min. In addition, emission-line flaring is found predominantly at twice the polarimetric period. These two findings are strong evidences in favour of the presence of a magnetic white dwarf in the system. We interpret the measured periodicities in the context of our magnetic accretion model for SW Sex stars. In contrast with LS Pegasi - the first SW Sex star discovered to have modulated circular polarization - the polarization in RXJ1643.7+3402 is suggested to vary at 2(ω - Ω), while the emission lines flare at (ω - Ω). However, a 2ω/ω interpretation cannot be ruled out. Together with LS Peg and V795 Her, RXJ1643.7+3402 is the third SW Sex star known to exhibit modulated circular polarization.
