Abstract

We obtain the first image of a parity-odd celestial body. Recently, an intriguing parity-odd rotating boson star was proposed. We investigate the lensing effects of these stars in detail. Our analysis demonstrates distinct gravitational distortions around these stars, clearly differentiating them from their parity-even counterparts. Furthermore, we analyze the conditions under which chaotic behavior appears in the images of ultra-compact stars.

奇偶对旋转玻色子恒星的透镜和光环

我们获得了奇偶天体的第一张图像。最近，一个有趣的奇偶对旋转玻色子星被提出。我们详细研究了这些恒星的透镜效应。我们的分析表明，这些恒星周围存在明显的引力扭曲，这明显地将它们与偶等恒星区分开来。此外，我们还分析了在超致密恒星图像中出现混沌行为的条件。
