论文摘要
当观察到其重复的NOVA爆发时，RS OPH在光学波长上持续显示出闪烁。在2006年爆发期间，闪烁的闪烁消失了，这在最近的2021年事件中重复。我们一直在监视RS OPH，以寻找2021年爆发后B波段闪烁的重新出现。在+210的第210天（从Nova Optical最大值计数）中，仍然没有闪烁（Sigma（B）<0.002 mag），在Sigma（B）= 0.008 Mag上出现在+224天= 0.008 mag，并升高到Sigma（B）= 0.029 Mag，Day +250 +250。在以下日期，幅度仍然很大，尽管有波动。 RS OPH恢复B波段静止的亮度在+225天左右开始，并在+260天完成。并行模式随后是系统亮度的上升和闪烁的重新出现，这证实了RS OPH在RS OPH中所起的核心作用，这是通过返回积聚磁盘的前爆发条件以及直接情节空间的RG风的重新填充。
RS Oph has persistently displayed flickering at optical wavelengths when observed away from its repeating nova outbursts. During the 2006 eruption the flickering disappeared, and this repeated during the recent 2021 event. We have been monitoring RS Oph looking for the reappearance of flickering at B-band following the 2021 outburst. The flickering was still absent (sigma(B)<0.002 mag) on day +210 (counted from nova optical maximum), appeared at sigma(B)=0.008 mag on day +224, and raised to sigma(B)=0.029 mag on day +250. On following dates the amplitude remained large, although fluctuating. The recovery of B-band quiescence brightness by RS Oph begun around day +225 and was completed by day +260. The parallel patterns followed by the rise in system brightness and the reappearance of flickering confirm the central role played in RS Oph by the return to pre-outburst conditions of the accretion disk and the refilling by the RG wind of the immediate circumstellar space.
