标题： Variation in the luminosity of Kerr quasars due to extra dimension in brane Randall-Sundrum model

摘要： 我们提出了一种替代性的理论方法，展示出在Randall-Sundrum模型中额外维度的存在如何能够估算Schwarzschild和Kerr黑洞视界的修正，并进一步探讨其在类星体准静态亮度变化中的可测量性，这种亮度变化可能由额外维度的印记引起，赋予了AdS5整体中膜世界场景的几何特性。 旋转效应通过膜世界效应在Kerr视界半径上的修正比在Schwarzschild（静态黑洞）半径上的更显著，并且由此导致Kerr黑洞类星体亮度的更大变化。 本文旨在研究由于类星体中心Schwarzschild和Kerr黑洞（BHs）吸积气体引起的亮度变化，同时也利用Randall-Sundrum模型研究膜世界效应对超大质量BHs亮度变化的影响。 显示英文摘要

摘要： We propose an alternative theoretical approach showing how the existence of an extra dimension in Randall-Sundrum model can estimate the correction in the horizon of Schwarzschild and Kerr black holes, and consequently its measurability in terms of the variation of quasar luminosity, which can be caused by a imprint of an extra dimension endowing the geometry of a brane-world scenario in an AdS5 bulk. The rotation effects cause a more prominent correction in Kerr horizon radius than in Schwarzschild (static black hole) radius, via brane-world effects, and the consequent bigger variation in the luminosity in Kerr black holes quasars. This paper is intended to investigate the variation of luminosity due to accretion of gas in Schwarzschild and Kerr black holes (BHs) in the center of quasars, besides also investigating the variation of luminosity in supermassive BHs by brane-world effects, using Randall-Sundrum model.
