中子星中簡并電子氣體的臨界磁化
發(fā)布時間:2019-03-29 13:30
【摘要】:中子星內(nèi)部的電子處于高度簡并或完全簡并的狀態(tài),電子磁矩(包括內(nèi)稟磁矩和朗道反磁矩)的取向不是隨機的,而是呈現(xiàn)出極強的磁化行為.考慮了磁化后的磁誘導(dǎo)方程要改寫,改寫后的方程添加了新的磁場生成項,更重要的改變是等效磁擴散系數(shù)變小了(順磁情況),在臨界情況(等效擴散系數(shù)等于零),磁場在磁生成項的作用下增加直到抑制機理出現(xiàn),朗道反磁矩就是在這個時候變得越來越重要.磁場增加的最終結(jié)果使中子星局域磁場成為振蕩的,對外看來有可能成為磁星.
[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.
