AI中文摘要：
本文讨论了球对称带电玻色子星及其冻结态时空中测试粒子的动力学。冻结态由德西特核心和黑洞外部构成，两者之间由有限厚度的壳层过渡。我们讨论了带电和不带电的有质量粒子，找到了ISCO（最内层稳定圆轨道），并确定靠近（冻结）玻色子星核心的有质量粒子碰撞是否会导致大的质心系能量。我们还讨论了无质量测试粒子，发现在冻结玻色子星时空中可能存在光子环和光点。我们将我们的结果与相应的Reissner-Nordstroem时空中的结果进行比较，并指出差异。
英文摘要：
In this paper, we discuss the dynamics of test particles in the space-time of spherically symmetric, charged boson stars and their frozen states. These latter objects consist of a de Sitter core and a black hole exterior with a shell of finite thickness interpolating between the two. We discuss charged and uncharged massive particles, find the ISCOs and determine whether collisions of massive particles close to the core of (frozen) boson stars can lead to large center of mass energies. We also discuss massless test particles and find that photons rings as well as light points are possible in the space-time of frozen boson stars. We compare our results with those in the corresponding Reissner-Nordstroem space-time and point out differences.
