论文摘要
本文提出了一个模型，通过从地壳中构建和释放弹性应力来统一磁性活性的各种范围。细胞自动机驱动地壳的局部和全球屈服，导致冠状环和能量释放的编织。该模型在许多方面都表现得像真正的磁性：巨型耀斑和小爆发都会发生，以及典型持续时间的静止时期，即$ \ sillesim 1 $ yr或$ \ sim 10-30 $ yr。爆发能量分布广泛地遵循了能量范围上的类似地震的力量定律$ 10^{40} -10^{45} \，{\ rm erg} $。冠状环的局部性质允许从同一磁场产生高能量和快速无线电爆发。在此范式中，磁性观测值可用于限制中子星形外壳的机械性能不佳。
This paper presents a model to unify the diverse range of magnetar activity, through the building and release of elastic stress from the crust. A cellular automaton drives both local and global yielding of the crust, leading to braiding of coronal loops and energy release. The model behaves like a real magnetar in many ways: giant flares and small bursts both occur, as well as periods of quiescence whose typical duration is either $\lesssim 1$ yr or $\sim 10-30$ yr. The burst energy distribution broadly follows an earthquake-like power law over the energy range $10^{40}-10^{45}\,{\rm erg}$. The local nature of coronal loops allows for the possibility of high-energy and fast radio bursts from the same magnetar. Within this paradigm, magnetar observations can be used to constrain the poorly-understood mechanical properties of the neutron-star crust.
