摘要

中子星包含有粒子的区域，这些粒子表现出磁矩，而磁矩反过来又产生各自的磁化。通过磁化与物质之间的磁弹性相互作用，产生磁致伸缩。磁致伸缩改变了中子星的质量密度，从而改变了它的惯性张量，结果它改变了恒星的旋转频率。结果表明，该效应以一种明显的非线性方式取决于中子星的磁化强度。我们还概述了如何计算中子星内部不同区域的磁致伸缩，以及需要哪些参数输入。

Magnetic Effect on the Rotation Frequency of a Neutron Star: An Intrinsically Nonlinear Effect

A neutron star contains regions with particles which exhibit magnetic moments, which, in turn, generate respective magnetizations. By magnetoelastic interactions between the magnetization and the matter there arises a magnetostriction. The magnetostriction changes the mass density of the neutron star and hence its inertia tensor, and as a result it changes the rotation frequency of the star. It is shown that the effect depends in a distinctly nonlinear way on the magnetization of the neutron star. We also sketch how the calculation of the magnetostriction in the different inner regions of the neutron star has to proceed, and which parameter inputs are needed.
