由旋量流体支持的静态和坍缩构型
Static and collapsing configurations supported by the spinor fluid
摘要：
我们研究了一个由旋量流体组成的引力球对称非相对论性组态，其有效状态方程是从一个由大质量非线性旋量场支持的极限系统的考虑中推导出来的。对于这样的配置，我们发现一个双参数家庭的静态正规解决方案描述紧凑的对象，其质量和大小是由中心密度的旋量流体和旋量场的质量。利用相似方法，我们考虑了由旋量流体组成的初始均匀系统的引力坍缩。我们估计的崩溃的一般特征，并表明，由此产生的流体的不均匀分布发生，可能作为一个核心的平衡星形配置的创建。
英文摘要：
We study a gravitating spherically symmetric nonrelativistic configuration consisting of a spinor fluid whose effective equation of state is derived from a consideration of a limiting system supported by a massive nonlinear spinor field. For such a configuration, we find a two-parametric family of static regular solutions describing compact objects whose masses and sizes are determined by the central density of the spinor fluid and the mass of the spinor field. Using the similarity method, we consider a gravitational collapse of an initially uniform system consisting of the spinor fluid. We estimate the general characteristics of the collapse and show that a resulting nonuniform distribution of the fluid occurs that may serve as a core for the creation of equilibrium starlike configurations.
