摘要:

我们报告空的结果,两年的光度搜索在SS天鹅座爆发的预测。在两个观测季节中,几乎每天都在约翰逊V号和约翰逊I号上进行多小时的观测。通过各种统计和视觉分析技术,积累的数据,但未能发现任何突出的预测。然而,对102年的AAVSO档案视觉数据的分析导致检测到大约1,000 - 2,000天长度的长期准周期特征与爆发率增加之间的相关性。

英文摘要:

We report null results on a two year photometric search for outburst predictors in SS Cyg. Observations in Johnson V and Cousins I were obtained almost daily for multiple hours per night for two observing seasons. The accumulated data are put through various statistical and visual analysis techniques but fails to detect any outburst predictors. However, analysis of 102 years of AAVSO archival visual data led to the detection of a correlation between a long term quasi-periodic feature at around 1,000-2,000 days in length and an increase in outburst rate.
