【摘要】：在很多低/硬态X射线双星系统(XRB)中,射电和X射线光度之间存在较好的相关关系.Dong等人通过研究得出了射电静类星体(RQQ)也存在着这一关系,并且其关系式与低/硬态X射线双星的基本面关系有着一定的相似度.分析收集的射电噪类星体来探究射电噪类星体是否也存在着这种关联,这些源包含了255个射电噪类星体.分析结果表明:(1)255个射电噪类星体(RLQ)的黑洞质量与X射线和射电光度之间以及射电光度爱丁顿比率和X射线爱丁顿比率之间均存在相关性,这与Dong等人运用亮硬态黑洞双星和射电噪类星体所得出的基本面关系式有一定的相似性,但仍然存在一定差异.(2)低/硬态X射线双星与射电噪类星体的基本面关系式可统一为lg L_R=0.998~(+0.045)_(-0.045)lg L_X+0.592~(+0.049)_(-0.049)lg M_(BH)-6.56~(+1.605)_(-1.605)(其中L_R为射电光度,L_X为X射线光度,M_(BH)为黑洞质量).(3)研究结果进一步证明了X射线和射电光度与黑洞质量所构成的基本面关系式具有高度的统一性,不仅可用于描述低/硬态X射线双星系统和射电静类星体,同样可用于射电噪类星体.
[Abstract]:In many low / hard X-ray binary systems XRBs. There is a good correlation between radio and X-ray luminosity. Dong et al. Obtained the same relationship between radio static quasar RQQ). And its relationship has certain similarity with the fundamental relation of low / hard X-ray binary star. Analyze the collected radio noise quasars to find out whether the radio noise quasars also exist this correlation. These sources contain 255 radio noise quasars. The analytical results show that: 1) 255 radio noise quasars RLQ). There is a correlation between the mass of black hole and X-ray and radio luminosity, as well as between the radio luminosity Eddington ratio and X-ray Eddington ratio. This is similar to the fundamental equation obtained by Dong et al using bright hard black hole binaries and radio noise quasars. However, there is still some difference between low / hard X-ray binary stars and radio noise quasars. The basic relation formula can be unified as LG LRN 0.998 (0.045 / 0. 045). _ _ _. Among them, L _ S _ R was radio luminosity. The results of the study further prove that the fundamental relation between X-ray and radio luminosity and black hole mass has a high degree of unity. It can be used not only to describe low / hard X-ray binary systems and radio static quasars, but also to describe radio noise quasars.
