Polarization and Radiation Geometry of PSR B1937+21

Lu, Jiguang

The PPA curves of PSR B1937+21 in weak radiation regions can be fitted by the RVM model, then a dipole magnetic field is supposed. The multipolar field model can indeed be used to explain some confusing phenomena, but sometimes it need not necessarily be introduced. With "the Occam's Razor" in mind, the necessity of invoking a multipolar field should be considered carefully.
