活动星系核在光学波段的光度及光谱斜率变化

AGN Variability and Spectral Slope Variability in the Optical Band

利用盘不稳定模型和星爆模型,模拟活动星系核在光学B、V波段的光变,分析光变时光谱斜率的变化情况,并将模拟的结果和观测进行比较,结果表明,这两种模型是定性解释活动星系核光学波段光度、光谱变化的合理模型.

With disk-instability model and starburst model, AGN optical variability and spectral slope variability in the B and V bands are simulated and compared with observations. The results show that disk-instability model and starburst model can qualitatively explain the variability and spectral slope variability in the optical band.
