【摘要】：為研究耀變天體3C 454.3高能光變行為,采用結(jié)構(gòu)函數(shù)和離散關(guān)聯(lián)函數(shù)法對(duì)該源近8年Fermi/LAT伽瑪波段流量監(jiān)測(cè)結(jié)果進(jìn)行分析。結(jié)構(gòu)函數(shù)分析表明:近8年的高能光變中存在多個(gè)特征光變時(shí)標(biāo),最小特征光變時(shí)標(biāo)6 d;寧?kù)o態(tài)前后兩段不同光變幅度的伽瑪光變有類(lèi)似變化趨勢(shì),均有最小特征光變時(shí)標(biāo)6 d;整個(gè)光變存在可能周期230 d和350 d,與離散關(guān)聯(lián)函數(shù)分析得到的周期223 d和351 d近似一致。根據(jù)周期分析理論,推斷耀變天體3C 454.3伽瑪波段光變存在周期(226±3.5)d和(250±0.5)d。與以前的研究結(jié)果對(duì)比,耀變體3C 454.3高能光變存在雙周期是一個(gè)新發(fā)現(xiàn)。
[Abstract]:In order to study the high-energy light variation behavior of 3C 454.3 object, the structure function and discrete correlation function method are used to analyze the Fermi/LAT gamma-band flow monitoring results of the source in the last eight years. The structural function analysis shows that there are several characteristic light varying time scales in the last eight years, and the minimum characteristic light varying time scales are 6 days, and the gamma light changes with different light variation amplitude in the two sections before and after the static state have a similar trend. The existence of the whole phototransformer is likely to be 230 d and 350 d, which is approximately consistent with the 223d and 351d periods obtained by the discrete correlation function analysis. Based on the theory of periodic analysis, it is inferred that there are 2263.5d and 250 鹵0.5d periods for 3C 454.3 gamma-band photovoltaics. Compared with the previous results, it is a new discovery that there exists a double period of 3C 454.3 high energy photovariances.
