论文摘要
我们表明，由于旋转天体物理体的弯曲时空中的惯性框架拖动惯性框架引起的自旋脱位破坏了原始种子磁场。该种子磁场即使是由于中性中子等电中性费米子也会引起的。例如，我们表明，理想的中子星每秒以$ 500 $的转速旋转，质量为$ 0.83 $ m $ _ {\ odot} $，并通过一组简并中子的合奏来描述，将在其中心$ 0.12 $ gauss seed磁场在其中心出现。
We show that a primeval seed magnetic field arises due to spin-degeneracy breaking of fermions caused by the dragging of inertial frames in the curved spacetime of rotating astrophysical bodies. This seed magnetic field would arise even due to electrically neutral fermions such as neutrons. As an example, we show that an ideal neutron star rotating at $500$ revolutions per second, having mass $0.83$ M$_{\odot}$ and described by an ensemble of degenerate neutrons, would have $0.12$ Gauss seed magnetic field at its center arising through the breaking of spin-degeneracy.
