TL;DR
This paper explores how the geometry of neutron stars, specifically the angle between their rotation and magnetic axes, influences the observable phenomena of various anomalous pulsars, including AXPs, SGRs, RRATs, CCOs, and XDINSs.
Contribution
It proposes that differences among anomalous pulsars can be explained by their magnetic inclination angle, affecting their magnetospheric processes and observable behaviors.
Findings
Aligned rotators (BETA < 10°) exhibit drift wave effects influencing periodicity.
Nearly orthogonal rotators (large BETA) may show modulation due to accretion from surrounding media.
Geometry-dependent mechanisms can unify understanding of diverse anomalous pulsar phenomena.
Abstract
Many astrophysicists believe that Anomalous X-Ray Pulsars (AXP), Soft Gamma-Ray Repeaters (SGR), Rotational Radio Transients (RRAT), Compact Central Objects (CCO), and X-Ray Dim Isolated Neutron Stars (XDINS) belong to different classes of anomalous objects with neutron stars as the central bodies inducing all their observable peculiarities. We have shown earlier (I.F.Malov and G.Z.Machabeli, Astron. Astrophys. Trans. 25, 7, 2006) that AXPs and SGRs could be described by the drift model in the framework of preposition on usual properties of the central neutron star (rotation periods P ~ 0.1 - 1 sec, surface magnetic fields B ~ 10^11 - 10^13 G). Here we shall try to show that some differences of considered sources will be explained by their geometry (particularly, by the angle BETA between their rotation and magnetic axes). If BETA < 10 deg. (the aligned rotator) the drift waves at the…
