论文摘要
我们研究了58个监测光曲线（LCS）的复发性NOVA RS OPH的光度法，这是由5个望远镜采取的。所有LCS在时间尺度上均在几分钟到几个小时的时间尺度上显示出重复的时间结构（QPS）。在我们先前的工作中，在LCS中通过局部结构函数和自动相关函数的局部最大值检测到97 QP。 QPS的分布在8、13、21、30、48和73分钟时显示模式，其中8分钟的模式揭开了不当。这些模式遵循基本$ 1.55 \ 3/2 $的功率功能，标准偏差为4.7％。该功能预测模式在5.3和3.5分钟处，这些模式在完整的MLC中未检测到。在目前的工作中，我们分析了高分辨率LCS的简单小部分。我们在8.0、5.3和3.5分钟处确认QPS模式。通常，我们在时间间隔3.5-73分钟内发现了8个具有常规对数分布的QP模式。我们还显示了QP模式的典型的QP模式的典型夜间演变 - 从一个QP模式到另一种QP模式的锐利或逐渐过渡。最后，我们发现LCS的各个部分在短时间内具有整个LCS的特性。这导致了两个良好的依赖性 - 在LC的范围偏差和标准偏差之间以及LC的密度函数的相关水平之间。
We study the photometric behavior of the recurrent nova RS Oph by 58 monitoring light curves (LCs), taken by 5 telescopes. All LCs show repeating time structures with some quasi-periods (QPs) in time scales from minutes to hours. In our previous work 97 QPs were detected in the LCs by local minimums of structure functions and local maximums of auto-correlation functions. The distribution of the QPs shows modes at 8, 13, 21, 30, 48 and 73 min, where the mode at 8 min is poorly unveiled. These modes follow a power function with base $1.55\approx 3/2$ with standard deviation 4.7%. This function predicts modes also at 5.3 and 3.5 min, which are not detected in the full MLCs. In the present work we analyze simple small parts from high resolution LCs. We confirm the QPs modes at 8.0, 5.3 and 3.5 min. Generally, we found 8 QP modes with regular logarithmic distribution in the time interval 3.5-73 min. We also show typical intra-night evolutions of QP modes in the minute scale -- sharp or gradual transitions from one QP mode to other. In the end we find that the parts of the LCs carry out the properties of the whole LCs at short time scale. This lead to two well pronounces dependences - between the range deviation and standard deviation of the LC, as well as between the quasi-period and the relevant level of the density function of the LC.
