该研究探讨了静态、球对称虫洞几何中薄吸积盘的物理性质和特征，对比了与施瓦茨希尔德黑洞的差异。结果显示，虫洞几何中的吸积盘能释放出比黑洞更多能量，辐射效率提高一倍以上。温度分布的径向剖面和发射光谱进一步证实了这些效应，表明虫洞在电磁谱中存在独特的标识，为区分虫洞几何提供了可能。
摘要：
In this paper, we study the physical properties and characteristics of matter forming thin accretion disks in static and spherically symmetric wormhole spacetimes. In particular, the time averaged energy flux, the disk temperature, and the emission spectra of the accretion disks are obtained for these exotic geometries and are compared with the Schwarzschild solution. It is shown that more energy is emitted from the disk in a wormhole geometry than in the case of the Schwarzschild potential and the conversion efficiency of the accreted mass into radiation is more than a factor of 2 higher for the wormholes than for static black holes. These effects in the disk radiation are confirmed in the radial profiles of temperature corresponding to theses flux distributions, and in the emission spectrum ωL(ω) of the accretion disks. We conclude that specific signatures appear in the electromagnetic spectrum, thus leading to the possibility of distinguishing wormhole geometries by using astrophysi
