We find a new class of exact solutions in the Einstein-Maxwell theory by employing the Ernst magnetization process to the Kerr-Newman-Taub-NUT spacetimes. We study the solutions and find that they are regular everywhere. We also find the quasilocal conserved quantities for the spacetimes, the corresponding Smarr formula and the first law of thermodynamics.
通过对克尔 - 纽曼 - 陶布 - 纽特时空应用恩斯特磁化过程,我们在爱因斯坦 - 麦克斯韦理论中找到了一类新的精确解。我们研究了这些解,发现它们在各处都是正则的。我们还找到了这些时空的准局域守恒量、相应的斯马尔公式以及热力学第一定律。
