中子星中简并电子气体的临界磁化
发布时间：2019-03-29 13:30
【摘要】：中子星内部的电子处于高度简并或完全简并的状态,电子磁矩(包括内禀磁矩和朗道反磁矩)的取向不是随机的,而是呈现出极强的磁化行为.考虑了磁化后的磁诱导方程要改写,改写后的方程添加了新的磁场生成项,更重要的改变是等效磁扩散系数变小了(顺磁情况),在临界情况(等效扩散系数等于零),磁场在磁生成项的作用下增加直到抑制机理出现,朗道反磁矩就是在这个时候变得越来越重要.磁场增加的最终结果使中子星局域磁场成为振荡的,对外看来有可能成为磁星.
[Abstract]:The electron in neutron star is in a highly degenerate or completely degenerate state, and the orientation of electron magnetic moment (including intrinsic magnetic moment and Landau antimagnetic moment) is not random, but shows extremely strong magnetization behavior. The magnetic induction equation after magnetization is considered to be rewritten, and a new magnetic field generation term is added to the rewritten equation. The more important change is that the equivalent magnetic diffusion coefficient decreases (paramagnetic case), in the critical case (equivalent diffusion coefficient equals zero), The magnetic field increases under the action of magnetic terms until the inhibition mechanism appears, and the Landau diamagnetic moment becomes more and more important at this time. The final result of the magnetic field increase makes the local magnetic field of neutron stars oscillate, which seems likely to become a magnetic star.
