【摘要】:运用含时演化理论模型研究脉冲星风云G21.5-0.9的多波段非热辐射.在这个模型中,考虑2种不同成分的注入电子,低能成分电子和高能成分电子.其中低能成分电子形式为具有幂律谱,而高能成分电子形式为Maxwellian加上一个高能幂律谱.通过理论计算,发现该模型能很好地解释脉冲星风云G21.5-0.9的多波段观测数据,射电到X射线段的辐射主要通过电子同步辐射产生,而伽玛射线主要通过逆康普顿散射产生.
[Abstract]:The multiband nonthermal radiation of pulsar wind cloud G21.5-0.9 is studied by using the time-dependent evolution theory model. In this model, two kinds of injected electron, low energy component electron and high energy component electron are considered. The low energy component electron form is a power law spectrum, while the high energy component electron form is Maxwellian plus a high energy power law spectrum. Through theoretical calculation, it is found that the model can well interpret the multi-band observation data of pulsar wind and cloud G21.5-0.9, and the radiation from radio to X-ray is mainly produced by electron synchrotron radiation. Gamma rays are mainly produced by inverse Compton scattering.
