活动型SU UMa型矮新星超循环长度的增加

Increasing supercycle lengths of active SU UMa-type dwarf novae

M. Otulakowska-Hypka, A. Olech

摘要:

我们目前的观测证据表明,在过去的几十年中,最活跃的SU UMa型恒星的超周期长度正在增加。我们分析了大量的光度测量,从现有的档案,发现这种效果是通用的这类恒星,独立于他们的演化状态。这一发现与之前的预测和Patterson等人(2012)对BK Lyn的最新研究一致。

英文摘要:

We present observational evidence that supercycle lengths of the most active SU UMa-type stars are increasing during the past decades. We analysed a large number of photometric measurements from available archives and found that this effect is generic for this class of stars, independently of their evolutionary status. This finding is in agreement with previous predictions and the most recent work of Patterson et al. (2012) on BK Lyn.
