三维脉冲星同步加速器:曲率辐射

The pulsar synchrotron in 3D: curvature radiation

Ioannis Contopoulos, Constantinos Kalapotharakos

摘要:

通过对旋转磁偶极子的三维数值模拟,研究了脉冲星闭合线区尖端的强电流片。我们表明,曲率辐射的相对论性电子和正电子在电流片可以自然地解释高能脉冲星发射的几个功能。我们得到的光变曲线和偏振剖面的完整范围内的磁场倾斜角和观察者的取向,并比较我们的结果从费米伽马射线望远镜的最新观测。

英文摘要:

We investigate the strong electric current sheet that develops at the tip of the pulsar closed line region through time dependent three-dimensional numerical simulations of a rotating magnetic dipole. We show that curvature radiation from relativistic electrons and positrons in the current sheet may naturally account for several features of the high-energy pulsar emission. We obtain light curves and polarization profiles for the complete range of magnetic field inclination angles and observer orientations, and compare our results to recent observations from the Fermi gamma-ray telescope.
