论文摘要
爱因斯坦 - 斯卡尔 - 高斯 - 骨网络重力最近已知会表现出自发的标态化。在存在高斯式术语的情况下，除了一般的相对论溶液外，还发现了具有非平凡标量场磁场的新型黑洞溶液，并具有新的黑洞溶液。在本文中，我们旨在研究观察测试爱因斯坦 - 斯卡尔 - 高斯 - 骨网络重力，并使用这种标量的黑洞周围的薄积聚磁盘性能。使用Novikov-Thorne模型，我们通过数值计算电磁通量，温度分布，发射光谱，最内向的稳定圆形轨道以及围绕此类黑洞的积聚磁盘的能量转换效率，并将结果与标准的一般相对论Schwarzschilzschild解决方案进行比较。我们发现，标量的黑洞周围的积聚磁盘比一般相对论更热，更发光。
Einstein-scalar-Gauss-Bonnet gravity has recently been known to exhibit spontaneous scalarization. In the presence of the Gauss-Bonnet term the no-hair theorem can be evaded and novel black hole solutions with non-trivial scalar fields have been found besides the general relativistic solutions. In this paper, we aim to investigate the possibility of observationally testing Einstein-scalar-Gauss-Bonnet gravity using thin accretion disk properties around such scalarized black holes. Using the Novikov-Thorne model, we numerically calculate the electromagnetic flux, temperature distribution, emission spectrum, innermost stable circular orbits and energy conversion efficiency of accretion disks around such black holes and compare the results with the standard general relativistic Schwarzschild solution. We find that the accretion disks around scalarized black holes are hotter and more luminous than in general relativity.
