论文摘要
极点是高度磁性的变量，长期以来一直观察到具有高亮度状态和低亮度状态。以前，这些州的持续时间从最多的几天到数年有所不同。尽管如此;这些状态及其身体起源并未以一致的方式解释。我们介绍了ZTF和TESS观察到的许多极点的最短持续时间状态。这使我们能够确定短持续状态是在Polars种群中相对常见的特征。此外，我们已经能够通过在白色矮人的磁场和恒星斑点之间的相互作用来概括恒星点迁移的模型，以解释极点的短状态和低状态。
Polars are highly magnetic cataclysmic variables which have been long observed to have both high and low brightness states. The duration of these states has been previously seen to vary from a number of days up to years. Despite this; these states and their physical origin has not been explained in a consistent manner. We present observations of the shortest duration states of a number of Polars observed by ZTF and TESS. This has allowed us to determine that short duration states are a relatively common feature across the population of Polars. Furthermore we have been able to generalise the model of star spot migration to explain both short lived high and low states in Polars by incorporating the interaction between the magnetic field of the white dwarf and that of the star spots.
