摘要:

研究了强磁场作用下中子星(含超子和不含超子)的量子强子动力学状态方程。推导出的质量和半径是一致的高质量中子星,即使在足够强的磁场的情况下的超音核的最近的观察。计算得到的磁化中子星的绝热指数和转动惯量随密度变化迅速。这可能提供一些洞察力的机制,星震和耀斑的磁星。

英文摘要:

We investigate the quantum hadrodynamic equation of state for neutron stars (with and without including hyperons) in the presence of strong magnetic fields. The deduced masses and radii are consistent with recent observations of high mass neutron stars even in the case of hyperonic nuclei for sufficiently strong magnetic fields. The calculated adiabatic index and the moments of inertia for magnetized neutron stars exhibit rapid changes with density. This may provide some insight into the mechanism of star-quakes and flares in magnetars.
