Abstract

We consider the influence of space curvature in the Schwarzschild metric on the contribution of the magnetic field outside the neutron star to the moment of inertia of a radio pulsar. Our consideration is restricted only to the simplest configuration of the magnetic field, when it can be described by only one harmonic. We show that at a fixed magnetic field strength on the stellar surface the influence of space curvature reduces the contribution of the magnetic field outside the star to the departure of the inertia tensor from the spherical one several-fold.

空间曲率对脉冲星磁场转动惯量的影响

摘要

我们考虑史瓦西度规中的空间曲率对中子星外部磁场对射电脉冲星惯性矩贡献的影响。我们的考虑仅限于磁场的最简单配置，此时它只能用一种谐波来描述。我们表明，在恒星表面磁场强度固定的情况下，空间曲率的影响使恒星外部磁场对惯性张量偏离球形惯性张量的贡献降低了几倍。
