长期观测显示,耀变体S5 0716+714具有复杂的光变行为. 本文运用混沌理论,研究了S5 0716+714四个较大爆发阶段的射电、光学和X波段的光变曲线. 分别计算了它们的关联维和Lyapunov指数. 结果表明: 1)光变曲线的关联维和Lyapunov指数都介于纯混沌系统与随机噪声之间;2)相轨迹是一个与Rossler吸引子相似的混沌系统,由于受到各种内在或外在因素的影响产生噪声,导致关联维和Lyapunov指数均比Rossler吸引子大,相轨迹出现紊乱. 从这两个混沌判据上看,三个波段均表现出很强的混沌特性,因此推断S5 0714+716的光变是一个混沌现象.

Long-term observations show that blazar object S5 0716 +714 has complicated behavious on multiband. In this paper, the light curves in the radio, V-band and X-ray bands of four outbursts are studied by the chaos theory. We calculate their correlation dimensions and Lyapunov exponents and find that 1) these two values are in a range between a stochastic system and a pure chaotic system; 2) the phase locus of S5 0716 +714 is a chaotic system similar to the Rossler attractor. Various internal or external factors may produce noises, resulting in the fact that the correlation dimension and Lyapunov exponent may be higher than those of the Rossler attractor and the phase locus might be orderless. According to our analysis, we conclude that the light curves of S5 0714+716 show some chaotic features and the variability of this source may be a chaotic phenomenon.-
