论文摘要
令人惊讶的是，围绕Gibbons-Maeda-Garfinkle-Horowitz-Strominger（GMGHS）异性弹性理论的Gibbons-Maeda-Garfinke-Horowitz-Strominger（GMGHS）围绕Gibbons-Maeda-Garfinkle-Horowitz-Strominger（GMGHS）的发射磁盘的发射率（\ textit {àla}页面和索恩）似乎尚未被研究。为了填补文献中的这一空白，我们使用Page-Thorne模型研究了爱因斯坦和弦框架中这些黑洞周围薄积聚磁盘的发射率。为了进行说明，我们选择作为玩具模型，它是恒星大小的球形对称黑洞，发现，虽然发射率与Reissner-Nordström和Schwarzschild黑洞的发射率并没有显着差异，但它们在GMGHS的极端限制在较高的频率上与裸露的奇异性和蠕虫相通用。这些差异提供了一种新颖的方式，可以从观察的角度从不同类型的对象进行投机性结论。
It seems surprising that the emissivity properties of the accretion disk (\textit{à la} Page and Thorne) surrounding the Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) black holes of heterotic string theory have not yet been studied. To fill this gap in the literature, we study the emissivity properties of the thin accretion disks around these black holes both in the Einstein and in the string frame using the Page-Thorne model. For illustration, we choose as a toy model a stellar-sized spherically symmetric black hole and find that, while the emissivity properties do not significantly differ from those of Reissner-Nordström and Schwarzschild black holes, they remarkably differ at GMGHS extreme limits corresponding to naked singularity and wormhole at higher frequencies. These differences provide a novel way to speculatively conclude about different types of objects from the observational point of view.
