论文摘要
中子星内部组成探索器（MID）观察到毫秒Pulsar PSR J0030+0451的最新建模表明，脉冲星的磁场是非偶极的。我们构建了一个磁场配置，其中开放磁场线的脚点非常类似于从更好的观测值中的热点配置。使用此磁场作为输入，我们对PSR J0030+0451的磁层进行无力模拟，显示了其血浆充满磁层的三维结构。我们对发射区域进行简单且有动力的假设，我们能够构建与相应观察结果一致的多波长灯曲面。该协议表明，多极磁性结构是建模这种类型的脉冲星的关键，可用于限制磁性倾斜角和无线电发射的位置。
Recent modeling of Neutron Star Interior Composition Explorer(NICER) observations of the millisecond pulsar PSR J0030+0451 suggests that the magnetic field of the pulsar is non-dipolar. We construct a magnetic field configuration where foot points of the open field lines closely resemble the hotspot configuration from NICER observations. Using this magnetic field as input, we perform force-free simulations of the magnetosphere of PSR J0030+0451, showing the three-dimensional structure of its plasma-filled magnetosphere. Making simple and physically motivated assumptions about the emitting regions, we are able to construct the multi-wavelength lightcurves that qualitatively agree with the corresponding observations. The agreement suggests that multipole magnetic structures are the key to modeling this type of pulsars, and can be used to constrain the magnetic inclination angle and the location of radio emission.
