论文摘要
鉴于其对GRB余辉发射的重大影响，已广泛建议将毫秒的磁铁发动机存在于伽马射线爆发（GRB）现象中。在本文中，我们研究了磁铁发动机对超新星（SN）发射的影响，该发射与长GRB有关，具体来说，与SN 2006AJ/GRB 060218的观察数据相遇。SN2006aj。SN 2006AJ的出色双峰紫外线 - 紫外线 - 紫外（Uv-uv-opt）。通过拟合这些光曲线，我们证明了第一个峰可以通过磁性风能驱动的冲击的突破发射来很好地解释，而主要的超新星发射也部分由磁场的能量注入。磁场的磁场强度被限制为$ \ sim 10^{15} $ g，这与从长GRB的余滴发射中推断出的常见结果非常吻合。更详细地，进一步建议，如果可以满足某些特殊条件，那么超新星后期发射的紫外线过量也可能是由于脉冲星风星云（PWN）的非热发射泄漏所致。模型和SN 2006AJ观察之间的一致性表明，磁铁发动机可能无处不在，在GRB现象中可能无处不在，甚至进一步加强了它们与乳胶超新星现象的联系。
A millisecond magnetar engine has been widely suggested to exist in gamma-ray burst (GRB) phenomena, in view of its substantial influences on the GRB afterglow emission. In this paper, we investigate the effects of the magnetar engine on the supernova (SN) emission which is associated with long GRBs and, specifically, confront the model with the observational data of SN 2006aj/GRB 060218. SN 2006aj is featured by its remarkable double-peaked ultraviolet-optical (UV-opt) light curves. By fitting these light curves, we demonstrate that the first peak can be well accounted for by the breakout emission of the shock driven by the magnetar wind, while the primary supernova emission is also partly powered by the energy injection from the magnetar. The magnetic field strength of the magnetar is constrained to be $\sim 10^{15}$ G, which is in good agreement with the common results inferred from the afterglow emission of long GRBs. In more detail, it is further suggested that the UV excess in the late emission of the supernova could also be due to the leakage of the non-thermal emission of the pulsar wind nebula (PWN), if some special conditions can be satisfied. The consistency between the model and the SN 2006aj observation indicates that the magnetar engine is likely to be ubiquitous in the GRB phenomena and even further intensify their connection with the phenomena of superluminous supernovae.
