论文摘要
重力的替代理论和参数化偏差方法使黑洞溶液具有质量，电荷和角动量的其他参数。原则上，物质字段可能会受这些解决方案的其他参数的影响。我们通过静态的konoplya-zhidenko黑洞计算无质体旋转0波的吸收横截面，其特征在于质量项中引入的变形参数，并将其与众所周知的Schwarzschild黑洞的吸收和相同质量的吸收进行了比较。我们将我们的数值结果与在高频限制中的SINC近似进行比较，发现了极好的一致性。
Alternative theories of gravity and the parameterized deviation approach allow black hole solutions to have additional parameters beyond mass, charge and angular momentum. Matter fields could be, in principle, affected by the additional parameters of these solutions. We compute the absorption cross section of massless spin-0 waves by static Konoplya-Zhidenko black holes, characterized by a deformation parameter introduced in the mass term, and compare it with the well-known absorption of a Schwarzschild black hole with the same mass. We compare our numerical results with the sinc approximation in the high-frequency limit, finding excellent agreement.
