论文摘要
Lorentz-Violating（LV）方案通过Bumblebee Field Vector Field $B_μ$参与其中。自发对称性破坏使该场可以获取将LV生成系统中的真空期望值。从辐射文具的广义形式开始，轴向对称的黑洞度量标准已经发现了Kerr-Sen样溶液。我们计算了大黄蜂旋转黑洞时空中无效的大地测量公司提供的有效潜力。为系统中涉及的参数的不同变化，对阴影进行了素描。已经进行了仔细的调查，以研究洛伦兹违规进入图片时的阴影如何受到影响。还研究了辐射的排放速率以及它如何随LV参数$ \ ell $而变化。
Lorentz-Violating (LV) scenario gets involved through a bumblebee field vector field $B_μ$. A spontaneous symmetry breaking allows the field to acquires a vacuum expectation value that generates LV into the system. A Kerr-Sen-like solution has been found out starting from the generalized form of a radiating stationery axially symmetric black-hole metric. We compute the effective potential offered by the null geodesics in the bumblebee rotating black-hole spacetime. The shadow has been sketched for different variations of the parameters involved in the system. A careful investigation has been carried out to study how the shadow gets affected when Lorentz violation enters into the picture. The emission rate of radiation has also been studied and how it varies with the LV parameter $\ell$ is studied scrupulously.
