处于平衡态的双黑洞系统

Binary black hole system at equilibrium

Marco Astorino, Adriano Viganò

AI总结:

本文构造了四维真空广义相对论中双静态黑洞平衡构型的精确解析解,依靠外部引力场实现无弦、无支柱平衡,并分析其几何与黑洞热力学定律。

摘要:

本文给出了四维真空广义相对论的一个精确解析解,该解描述了一个由两个处于平衡态的静态黑洞组成的系统。在事件视界之外,该度规在曲率奇点和锥形奇点两方面都是完全正则的。两个 Schwarzschild(史瓦西)源之间的平衡由外部引力场维持,除引力之外不需要额外的物质场,也不需要弦或支柱。文中分析了该解的几何结构,并讨论了 Smarr 定律以及黑洞热力学第一定律和第二定律。

英文摘要:

An exact and analytical solution of four dimensional vacuum General Relativity representing a system of two static black holes at equilibrium is presented. The metric is completely regular outside the event horizons, both from curvature and conical singularities. The balance between the two Schwarzschild sources is granted by an external gravitational field, without the need of extra matter fields besides gravity, nor strings or struts. The geometry of the solution is analysed. The Smarr law, the first and the second law of black hole thermodynamics are discussed.
