摘要：
我们研究了所谓的Einstein-Friedberg-Lee-Sirlin（E-FLS）理论中的静态玻色子星解，对该模型的解空间进行了完整分析。我们研究了E-FLS星的现象学特征，例如通过研究类时和类空测地线，重点分析了圆形类时轨道和光环。为了研究此类恒星的天体物理特征，我们考虑将其被几何薄吸积盘包围，从而获得了它们的图像。我们的结果包含两种不同的吸积盘模型，即光学薄盘和厚盘模型。我们展示了E-FLS星天体物理图像的部分发现，并讨论了其作为潜在黑洞模拟物的相关性。
英文摘要：
We investigate the static boson star solutions in the so-called Einstein-Friedberg-Lee-Sirlin (E-FLS) theory, performing a complete analysis of the solution space in this model. We study the phenomenological aspects of E-FLS stars, for instance, by investigating the timelike and null geodesics with an emphasis on the analysis of circular timelike orbits and light rings. In order to study the astrophysical signatures of such stars, their images were obtained considering them surrounded by a geometrically thin accretion disk. Our results comprise two different models of accretion disks, namely the optically thin and thick disk models. We present a selection of our findings for the astrophysical images of E-FLS stars and discuss their relevance as a possible black hole mimicker.
