RX J2115-5840: confirmation of a new near-synchronous polar
arXiv:astro-ph/9809314 · doi:10.1046/j.1365-8711.1999.02213.x
Abstract
Schwope et al (1997) suggested that the newly discovered Polar RX J2115-5840 is a near-synchronous system. We have obtained circular polarisation observations of RX J2115-5840 which show that the spin and orbital periods differ by 1.2%. We find the first direct evidence of `pole-switching' in a near-synchronous Polar. Further our data requires that the accretion flow must be directed onto the same magnetic field line at all spin-orbit beat phases implying that at some phases the flow must follow a path around the white dwarf before accreting.
