论文摘要
我们研究了旋转祖细胞恒星Kerr黑洞的重力崩溃和形成。我们遵循黑洞自旋的演变，以及其质量增加。我们研究了祖细胞包膜中不同旋转水平的效果，并在最终的黑洞参数上取得了一些约束。我们的方法基于半分析计算，涉及不同祖细胞的恒星进化模型。我们还通过一般相对论的MHD建模在数值上遵循黑洞的演化和时空度量的变化。 （简略）
We study the gravitational collapse and formation of the Kerr black hole from the rotating progenitor star. We follow the evolution of black hole spin, coupled with its increasing mass. We study the effect of different level of rotation endowed in the progenitor's envelope, and we out some constraints on the final black hole parameters. Our method is based on semi-analytical computations that involve stellar-evolution models of different progenitors. We also follow numerically the black hole evolution and spacetime metric changes during the collapse, via General Relativistic MHD modeling. (abridged)
