论文摘要
我们提出了迅速旋转的中子恒星,其中心有虫洞。它们在幽灵标量场的存在下以总体相对性而产生。核物质是由状态的多粒子方程式描述的,为中子恒星提供了逼真的质量和半径。虫洞的大小高达3 km。随着蠕虫尺寸的增加,恒星的质量和半径降低,而这些旋转混合中子恒星孔孔系统的存在域则保留了旋转中子星形结构域的特性。简要讨论了所考虑的混合配置的稳定性问题。
We present rapidly rotating neutron stars featuring wormholes in their centers. They arise in general relativity in the presence of a ghost scalar field. The nuclear matter is described by a polytropic equation of state, yielding realistic masses and radii for the neutron stars. The wormholes possess small circumferential radii of size up to 3 km. With increasing wormhole size, the masses and radii of the stars decrease, while the domain of existence of these rotating mixed neutron-star-plus-wormhole systems retains the characteristic properties of a rotating neutron star domain. The question of stability of the mixed configurations under consideration is briefly discussed.
