AI 中文摘要
在大质量恒星引力坍缩形成规则黑洞的过程中，为防止中心奇点形成，必须产生一种新形式的物质。由于初始恒星结构中不存在这种物质，它必定在坍缩过程中动态出现。此形成过程预计会伴随电磁辐射形式的强烈能量释放，可能可被观测到。我们研究了重子物质向戴姆尼科娃 - 海沃德 - 巴丁规则黑洞的引力坍缩。估计了由负责避免奇点的物质扇区形成所产生的辐射密度和相应的热光度。结果表明，此类过程为伽马射线暴提供了一种可能机制。此外，与伽马射线暴的兼容性要求正则化效应小。因此，相应的规则黑洞与史瓦西黑洞差异微弱。
英文摘要
During the gravitational collapse of a massive star into a regular black hole, a new form of matter must be produced in order to prevent the formation of a central singularity. Since such matter is not present in the initial stellar configuration, it must emerge dynamically during the collapse. This formation process is expected to be accompanied by a strong release of energy in the form of electromagnetic radiation, which may be observable. Here we investigate the gravitational collapse of baryonic matter into Dymnikova-Hayward-Bardeen regular black holes. We estimate the radiation density and the corresponding bolometric luminosity generated by the formation of the matter sector responsible for singularity avoidance. We show that such processes provide a possible mechanism for gamma-ray bursts. Moreover, compatibility with gamma-ray burst requires small regularization effects. As a result, the corresponding regular black holes differ weakly from the Schwarzschild black hole.
