摘要
本文计算和讨论了强磁场下由冷的催化物质组成的中子星外壳的组份和状态方程。文中考虑了晶格能和强磁场下均匀电子气体的交换能的贡献.得出结论:(1)强磁场使低密度区的状态方程变软;(2)强磁场对高密度区的状态方程几乎没有影响;(3)核质量公式对外壳的组份影响较明显.
Composition and equation of state in the outer crust of a neutron star, composed of cold catalyzed matter in a strong magnetic field, are calculated and discussed in this paper. The lattice and the exchange energies of an uniform electron gas in a strong magnetic field are considered. Three conclusions are drawn: (1) a strong magnetic field may soften equation of state at a low density region; (2) strong magnetic, field may hardly affect equation of state at a high density region; (3) a nuclear mass formula has an obvious effect on composition in the outer crust of a neutron star.
