【摘要】：運(yùn)用含時(shí)演化理論模型研究脈沖星風(fēng)云G21.5-0.9的多波段非熱輻射.在這個(gè)模型中,考慮2種不同成分的注入電子,低能成分電子和高能成分電子.其中低能成分電子形式為具有冪律譜,而高能成分電子形式為Maxwellian加上一個(gè)高能冪律譜.通過理論計(jì)算,發(fā)現(xiàn)該模型能很好地解釋脈沖星風(fēng)云G21.5-0.9的多波段觀測(cè)數(shù)據(jù),射電到X射線段的輻射主要通過電子同步輻射產(chǎn)生,而伽瑪射線主要通過逆康普頓散射產(chǎn)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.
