论文摘要
在存在强静态磁场的情况下，研究了与电磁辐射的空间局部和重力结合的轴突构型的能量交换速率。基于可分离的可分离时空结合谱而实现了完全分析的处理。对于稀轴恒星，将能量变化的方程重新解释为轴数的速率方程。它的解决方案暗示了渐近$ \ sim t^{1/5} $增加结块尺寸的$。
The rate of energy exchange of spatially localized and gravitationally bound axion configurations with electromagnetic radiation is investigated in presence of strong static magnetic field. Fully analytic treatment is achieved based on variationally optimized separable spatio-temporal clump profiles. For dilute axion stars the equation of the energy variation is reinterpreted as a rate equation of the axion number. Its solutions hints to an asymptotic $\sim t^{1/5}$ increase of the clump size.
