摘要:

本文提出了含宇宙学常数与不含宇宙学常数的bumblebee引力下的带电球对称黑洞解及缓转带电黑洞解。静态球对称解描述了类Reissner-Nordström黑洞与类Reissner-Nordström-(反)de Sitter黑洞,而定性轴对称解则描述了类Kerr-Newman黑洞与类Kerr-Newman-(反)de Sitter黑洞。我们采用Hamilton-Jacobi方法研究黑洞的阴影,此外还探究了电荷与洛伦兹破缺参数对阴影参考圆半径及形变参数的影响。研究发现,参考圆半径随洛伦兹破缺参数与电荷参数的增大而减小,而形变参数随二者的增大而增大。

英文摘要:

In this paper, we present charged spherically symmetric black hole solutions and slowly rotating charged solutions in bumblebee gravity with and without a cosmological constant. The static spherically symmetric solutions describe the Reissner-Nordström-like black hole and ReissnerNordström-(anti) de Sitter-like black hole, while the stationary and axially symmetric soltuions describe Kerr-Newman-like black hole and Kerr-Newman-(anti) de Sitter-like black hole. We utilize the Hamilton-Jacobi formalism to study the shadows of the black holes. Additionally, we investigate the effect of the electric charge and Lorentz-violating parameters on the radius of the shadow reference circle and the distortion parameter. We find that the radius of the reference circle decreases with the Lorentz-violating parameter and charge parameter, while the distortion parameter increases with the Lorentz-violating parameter and the charge parameter.
