This work will proceed to examine the dynamics of collapsing charged string cloud in a spherically symmetric rainbow metric. This is the framework that allows new stars and compact objects to emerge. The dynamical variables (mass density, string tension) and their physical existence as energy conditions are computed and visually depicted. We also calculated the duration and radius of development of the collapsing string cloud’s apparent horizons. The mass density, string tension, expected time and radius of apparent horizon creation are dependent on the Rainbow parameter η. At the center of the configuration R=0, the mass density, string tension and electric field intensity are at their maximum leading to the formation of a compact object (black hole). The fluid’s mass density and string tension are reduced by the electric field. Furthermore, the presence of an electric field delays the formation of a compact object (black hole).

彩虹引力下带电弦云坍塌动力学

这项工作将继续研究在球对称彩虹度量中坍缩带电弦云的动力学。这是允许新恒星和紧凑物体出现的框架。动态变量(质量密度、弦张力)及其作为能量条件的物理存在被计算并直观地描绘出来。我们还计算了坍缩弦云视界的持续时间和发展半径。质量密度、弦张力、预期时间和视层创建半径取决于 Rainbow 参数η.在配置的中心R=0,质量密度、弦张力和电场强度达到最大值,导致形成致密物体(黑洞)。电场会降低流体的质量密度和弦张力。此外,电场的存在延迟了致密物体(黑洞)的形成。
