费米子荷电玻色子星
Fermion-charged-boson stars
摘要：
费米子-玻色子星是由中子星的普通核物质和玻色子暗物质组成的类星系统。玻色子暗物质通常被认为是一个复杂的标量场。一个自然的扩展是复标量场是带电的。我们对U（1）下的标量场作了最简单的推广和规范。因此，我们研究费米子带电玻色子星。我们通过计算整个参数空间上的临界曲线，详细研究了该系统的稳定性。然后，我们研究如何费米子和玻色子部门有助于恒星的总质量。最后，我们提出了质量半径图，表明电荷的增加可以导致更大质量和更紧凑的恒星。
英文摘要：
Fermion-boson stars are starlike systems composed of the ordinary nuclear matter of a neutron star and bosonic dark matter. The bosonic dark matter has typically been taken to be a complex scalar field. A natural extension is for the complex scalar field to be charged. We make the simplest extension and gauge the scalar field under U(1). We therefore study fermion-charged-boson stars. We make a detailed study of the stability of this system by computing critical curves over the whole of parameter space. We then study how the fermion and boson sectors contribute to the total mass of the star. Finally, we present mass-radius diagrams, showing that an increase in charge can lead to more massive and more compact stars.
