论文摘要
我们讨论并实施了一种计算静止和轴对称黑洞溶液的光谱方法及其在修改后的重力理论中的特性。结果代码以朱莉娅的语言编写，并且是透明的，并且很容易适应新的设置。我们在一般相对论和爱因斯坦 - 斯卡尔 - 高斯 - 骨网重力上测试代码。它是准确且快速的，在这些理论中的旋转解决方案中会收敛，并在大多数情况下在大多数情况下（$ \ sim \ sim \ Mathcal {o} \ left（10^{ - 13} \ right）$）。
We discuss and implement a spectral method approach to computing stationary and axisymmetric black hole solutions and their properties in modified theories of gravity. The resulting code is written in the Julia language and is transparent and easily adapted to new settings. We test the code on both general relativity and on Einstein-Scalar-Gauss-Bonnet gravity. It is accurate and fast, converging on a spinning solution in these theories with tiny errors ($\sim \mathcal{O}\left(10^{-13}\right)$ in most cases) in a matter of seconds.
