高斯-博内引力下的黑洞初始数据:瞬时静态情形

Black hole initial data in Gauss-Bonnet gravity: Momentarily static case

Hirotaka Yoshino

摘要:

本文研究了在高斯-邦纳(GB)引力下黑洞系统初始数据的产生方法。初始数据被假定为瞬时静态的和共形平坦的。虽然共形因子的方程是高度非线性的,它是成功地解决了一个黑洞和两个黑洞系统的数值松弛。研究了双黑洞初始数据下的公共视视界,结果表明该系统满足Penrose不等式。这是在高曲率理论中模拟黑洞碰撞的第一步。

英文摘要:

We study the method for generating the initial data of black hole systems in Gauss-Bonnet (GB) gravity. The initial data are assumed to be momentarily static and conformally flat. Although the equation for the conformal factor is highly nonlinear, it is successfully solved by numerical relaxation for one-black-hole and two-black-hole systems. The common apparent horizon is studied in the two-black-hole initial data, and the result suggests that the Penrose inequalities are satisfied in this system. This is the first step for simulating black hole collisions in higher-curvature theories.
