超致密球对称暗物质带电星体

Ultra-compact spherically symmetric dark matter charged star objects

Bartłomiej Kiczek, Marek Rogatko

摘要:

研究了超致密球对称暗物质扇形星天体的性质,即两个$U(1)$ -规范场的爱因斯坦方程的解。其中之一是普通的麦克斯韦场,而辅助规范场属于隐藏扇区,并模仿暗物质的性质。可见扇区和隐藏扇区通过具有耦合常数$α$的动力学混合项耦合。我们还研究了带电标量场在反射的暗物质星体周围凝聚的可能性。碰巧的是,暗物质扇区,包括暗物质电荷和耦合常数,会导致恒星半径的收缩,从而可能发生凝聚。

英文摘要:

We study the properties of ultra-compact spherically symmetric dark matter sector star objects, being the solution of Einstein equations with two $U(1)$-gauge fields. One of them is the ordinary Maxwell field, while the auxiliary gauge field pertains to the hidden sector, and mimics the properties of dark matter. The visible and hidden sectors are coupled by a kinetic mixing term with a coupling constant $α$. We also investigate the possibility of condensation of charged scalar field around the reflecting dark matter star object. It happens that dark matter sector, both dark matter charge and coupling constant, cause shrinking of the star radius for which the condensation may occur.
