Constraints on the magnetic configuration of AP stars from simple features of observed quantities.
Abstract
According to the oblique rotator model, the time variations of the quantities usually employed to investigate the magnetic configuration of Ap stars (mean longitudinal field, mean surface field, broad band linear polarization) are described by simple laws. For each quantity, certain typical features can easily be identified. We show that these features set definite constraints on the magnetic configuration.
