论文摘要
我们研究了Kerr-Sen黑洞地平线附近光子的逃生概率。我们发现，如果光源在赤道附近，则光子的逃逸概率是非零的。我们表明，光子的逃逸概率随光源的径向位置而增加。还发现，如果恒定半径的光源从赤道平面移至极点，逃逸概率会降低。此外，我们发现卡特框架中光子的逃逸概率总是大于当地非旋转框架中的逃生概率，除了在杆上，它们相等。
We investigate the escape probabilities of the photons near the horizon of the Kerr-Sen black hole. We find that the escape probabilities of the photons are nonzero in the event horizon limit of the extreme Kerr-Sen black hole if the light sources are near the equator. We show that the escape probability of a photon increases with the radial position of the light source. It is also uncovered that the escape probability decreases if the light source with constant radius moves from the equatorial plane to the pole. Besides, we discover that the escape probability of a photon in the Carter frame is always greater than the one in the locally non-rotating frame, except on the pole, where they are equal.
