摘要
对37个耀变体的色指数与星等的关系进行了研究,结果表明BL Lac天体在天体变亮时颜色变蓝;而对于平谱射电类星体则存在变蓝和变红两种情况,分析表明这些现象是由激波喷流所引起.
The relationship of 37 blazars color index and magnitude are analyzed.We find that the BL Lacs exhibit bluer-when-brighter trends.FSRQs appeared in two cases,one exhibit redder-whenbrighter trends,the two exhibit bluer-when-brighter trends.The physical mechanism of these phenomena is discussed,and it is believed that this is caused by the shock-in-jet model.
