In this work, we calculated the toroidal magnetic field decay rates and magnetic energy decay rates by considering the general relativity effect of AXP 1E2259 + 586 associated with the supernova remnant CTB 109. The results confirmed that the high thermal radiation on the surface of the star could be attributed to Joule heating caused by the dissipation of crustal magnetic field. We also investigated the effects of ultrastrong magnetic fields on magnetization parameter and thermal conductivity in the crust.

AXP 1E 2259 + 586的磁热演化研究

在这项工作中，我们通过考虑AXP 1E2259 + 586与超新星余辉CTB 109相关的广义相对论效应，计算了环形磁场的衰减率和磁能衰减率。结果证实了恒星表面的高热辐射可能归因于地壳磁场耗散引起的焦耳热。我们还研究了超强磁场对地壳中磁化参数和导热系数的影响。
