Cyclotron humps in AM Her systems - V. Two poles in DP Leo

Abstract
We have modelled phase-resolved spectroscopic data of DP Leo to explain the appearance of an unusually strongly peaked cyclotron hump at 6100 Å. This can be modelled by emission from the second accretion region with almost twice the magnetic field of the main region (59 and 30.5 MG respectively). We show also that emission from such regions produces light and polarization curves which are consistent with observations.
