对称和非对称超新星遗迹中的X射线轮廓

X-rays profiles in symmetric and asymmetric supernova remnants

Lorenzo Zaninetti

摘要:

SN 1006 NE边缘的非热X射线呈现出特征标度长度,用相对论性电子扩散理论解释了这些特征标度长度,采用的理论框架是3D、1D和1D漂移的数学扩散以及1D漂移的MonteCarlo随机游走。非对称的平面扩散随机游走可以解释SN 1006的非热辐射强度的0.04pc上游和0.2pc下游的尺度宽度。本文还模拟了超新星遗迹的非热X射线通量的数学图象以及距中心距离的剖面函数。这个模型提供了SN 1006的边缘和中心区域的合理描述。本文提出了一种新的超新星遗迹磁场推算方法。

英文摘要:

The non-thermal X-rays from the SN 1006 NE rim present characteristic scale lengths that are interpreted in the context of diffusion of a relativistic electron. The adopted theoretical framework is the mathematical diffusion in 3D, 1D and 1D with drift as well as the Monte Carlo random walk in 1D with drift. The asymmetric random walk with diffusion from a plane can explain the scale widths of 0.04 pc upstream and 0.2 pc downstream in the non thermal intensity of X-ray emission in SN 1006. A mathematical image of the non thermal X-flux from an supernova remnant as well as profiles function of the distance from the center can be simulated. This model provides a reasonable description of both the limbs and the central region of SN 1006. A new method to deduce the magnetic field in supernova remnant is suggested.
