论文摘要
假设粒子源在Kerr-Sen黑洞的赤道平面上的局部非旋转框架中静止，我们研究了无质量粒子和从黑洞到空间无穷大的质量的逃逸。我们计算发射颗粒的逃生概率。我们发现，Kerr-Sen黑洞的角动量提高了极端Kerr-Sen黑洞地平线附近的逃生概率。但是，Kerr-Sen黑洞的角动量抑制了非极端Kerr-Sen黑洞的地平线附近的逃生概率。我们还发现，在某些条件下，Kerr-Sen黑洞的地平线限制并不是在粒子下逃脱的最困难位置。
Assuming that a particle source is at rest in a locally non-rotating frame on the equatorial plane of the Kerr-Sen black hole, we investigate the escape of the massless particle and massive particle from the black hole to spatial infinity. We calculate the escape probabilities of the emitted particles. We find that the angular momentum of the Kerr-Sen black hole boosts the escape probabilities near the horizon of the extreme Kerr-Sen black hole; however the angular momentum of the Kerr-Sen black hole suppresses the escape probabilities near the horizon of the non-extreme Kerr-Sen black hole. We also discover that the horizon limit of the Kerr-Sen black hole is not the most difficult position to escape for a particle in certain conditions.
