摘要:

我们进行了同时观察3个波段(UBV)的闪烁变化的经常性新星RS Oph和T CrB在静止。使用新的和已发表的数据,我们比较的颜色闪烁的灾难性的变量和共生经常新星。我们发现在这两种类型的吸积白矮星的闪烁源的颜色之间的差异。对于(U-B)与(B-V)图上的$(U-B)_0$颜色和$p \approx 3 \times 10^{-5}$分布,检测到的差异与$ p-value \approx 2 \times 10^{-6}$具有高度显著性。并简要讨论了可能的物理原因。这些数据可应作者的要求提供。

英文摘要:

We performed simultaneous observations in 3 bands (UBV) of the flickering variability of the recurrent novae RS Oph and T CrB at quiescence. Using new and published data, we compare the colours of the flickering in cataclysmic variables and symbiotic recurrent novae. We find a difference between the colours of the flickering source in these two types of accreting white dwarfs. The detected difference is highly significant with $ p-value \approx 2 \times 10^{-6}$ for the distributions of $(U-B)_0$ colour and $p \approx 3 \times 10^{-5}$ on (U-B) versus (B-V) diagram. The possible physical reasons are briefly discussed. The data are available upon request from the authors.
