A Study of Neutron Star Structure in Strong Magnetic Fields that includes Anomalous Magnetic Moments
Abstract
We study the effect of strong magnetic fields on the structure of neutron star. We find that if the interior field is on the same order as the surface field currently observed, then the influences of the field on the star's mass and radius are negligible; if the field is as large as that estimated from the scalar virial theorem, then considerable effects will be induced. The maximum mass of the star will be increased substantially while the central density is greatly reduced. The radius of a magnetic star can be larger by about 10% ∼ 20% than a nonmagnetic star of the same mass.
