具有超导核的磁化中子星：卷吸效应
Magnetized neutron stars with superconducting cores: Effect of entrainment
摘要：
我们用迭代数值方法构造磁化双流体中子星的平衡组态。在牛顿理论框架下，我们假设中子星有两个区域：核和壳，核是由II型超导质子和超流中子组成的双组分流体，壳是由正常物质组成的区域。采取一个新的步骤，更完整的平衡模型，我们包括夹带的影响，这意味着一个磁力作用在中子上，太。我们认为纯粹的极向场的情况下，并提出了改进的早期数值方案求解平衡方程，通过引入新的收敛标准。我们发现，夹带的结果在沿磁轴的磁力线结构的质的差异。
英文摘要：
We construct equilibrium configurations of magnetized, two-fluid neutron stars using an iterative numerical method. Working in Newtonian framework we assume that the neutron star has two regions: the core, which is modelled as a two-component fluid consisting of type-II superconducting protons and superfluid neutrons, and the crust, a region composed of normal matter. Taking a new step towards more complete equilibrium models, we include the effect of entrainment, which implies that a magnetic force acts on neutrons, too. We consider purely poloidal field cases and present improvements to an earlier numerical scheme for solving equilibrium equations, by introducing new convergence criteria. We find that entrainment results in qualitative differences in the structure of field lines along the magnetic axis.
