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.

磁化 Kerr-Newman-Taub-NUT 时空

我们通过将 Ernst 磁化过程应用于 Kerr-Newman-Taub-NUT 时空，在爱因斯坦-麦克斯韦理论中找到了一类新的精确解。我们研究了解决方案，发现它们在任何地方都是有规律的。我们还发现了时空的准局域守恒量、相应的 Smarr 公式和热力学第一定律。
