Numerical simulations of hairy black holes and boson stars

本博士课程的目标是玻色子星和毛状黑洞作为地基（LIGO/Virgo）和天基（丽莎）引力波探测器的引力波源的建模。虽然无毛定理强烈限制了黑洞被单个真实的标量场包围的可能性，但最近的研究表明，描述黑洞加复杂（振荡）标量场的爱因斯坦场方程存在定态解。这些解将著名的克尔解与纯标量星（称为玻色子星）联系起来。这里的具体目标是使用超级计算机在完全非线性广义相对论的框架内对这种配置进行建模，特别是测试这类新的多毛黑洞的稳定性，并计算这些物体的螺旋和合并中产生的引力波信号，包括作为限制情况的玻色子星。

Goal of this PhD course is the modeling of boson stars and hairy black holes as sources of gravitational waves for ground based (LIGO/Virgo) and space-based (LISA) gravitational wave detectors. While the no-hair theorems strongly constrain the possibility for black holes surrounded by single, real scalar fields, recent studies have shown that there exist stationary solutions to the Einstein field equations describing a black hole plus a complex (oscillatory) scalar field. These solutions connect the well known Kerr solution to pure scalar stars, called boson stars. The specific goal here is to model such configurations in the framework of fully non-linear general relativity using supercomputers and test in particular the stability of this new class of hairy black holes and calculate the gravitational wave signal generated in the inspiral and merger of these objects, including as a limiting case boson stars.
