论文摘要
已经表明，标量场可以形成称为玻色子星的重力绑定的紧凑物体。在这项研究中，我们分析了标量场含有少量角动量的玻色子星形构型，并找到两种新的溶液。在第一种情况下，所有颗粒处于相同的缓慢旋转状态，在第二种情况下，大多数粒子处于非旋转基态，少数颗粒处于激发的旋转状态。在这两种情况下，我们都求解了基本的Gross-pitaevskii-Poisson方程，这些方程式通过数值和分析性通过串联扩展来描述这些紧凑物体的曲线。
It has been shown that scalar fields can form gravitationally bound compact objects called boson stars. In this study, we analyze boson star configurations where the scalar fields contain a small amount of angular momentum and find two new classes of solutions. In the first case all particles are in the same slowly rotating state and in the second case the majority of particles are in the non-rotating ground state and a small number of particles are in an excited rotating state. In both cases, we solve the underlying Gross-Pitaevskii-Poisson equations that describe the profile of these compact objects both numerically as well as analytically through series expansions.
