论文摘要
我们在复杂标量场的耦合系统，U（1）量规场，复杂的Higgs标量场和Einstein Gravity中研究球形对称非物质孤子恒星（NTS恒星），其中对称性被自发地损坏。 NTS恒星的重力质量受到固定断裂尺度的最大质量的限制，并且随着断裂量表的减小，最大质量急剧增加。在断裂量表的情况下，NTS恒星的最大质量变成了天体物理量表，并且这种恒星在相对紧凑，因此它具有最内向的稳定圆形轨道。 第一作者贡献了数值计算的一部分。第二个是在计划和进行研究的过程中进行的，第三个是通过所有数值计算进行的，并找到了系统的新属性。
We study spherically symmetric nontopological soliton stars (NTS stars) numerically in the coupled system of a complex scalar field, a U(1) gauge field, a complex Higgs scalar field, and Einstein gravity, where the symmetry is broken spontaneously. The gravitational mass of NTS stars is limited by a maximum mass for a fixed breaking scale, and the maximum mass increases steeply as the breaking scale decreases. In the case of the breaking scale is much less than the Planck scale, the maximum mass of NTS stars becomes the astrophysical scale, and such a star is relativistically compact so that it has the innermost stable circular orbit. The first author contributed with a part of numerical calculations. The second did with planning and conducting the research, and the third did with all numerical calculations and finding new properties of the system.
