标题： Classifying optical (out)bursts in cataclysmic variables: the distinct observational characteristics of dwarf novae, micronovae, stellar flares and magnetic gating

摘要： 灾变变星可能会经历短暂的光学增亮，这些通常归因于如矮新星爆发、微新星、供体耀斑或磁门爆发等现象。 由于这些事件表现出相似的观测特征，其识别常常存在歧义。 特别是，磁门爆发和微新星已被建议作为同一现象的不同解释。 在这里，我们表明时间尺度和能量将光学增亮分为与不同分类一致的独立簇。 这表明微新星和磁门爆发实际上是不同的现象。 基于我们的发现，我们开发了诊断图，可以根据其特性区分这些爆发/耀斑。 我们通过观察新发现的中等极性天体CTCV J0333-4451来证明这种方法的有效性，我们将它分类为磁门系统。 CTCV J0333-4451是第三个具有高自转周期与轨道周期比的中等极性天体，具有磁门爆发，这表明这些爆发在这些罕见系统中是常见的。 显示英文摘要

摘要： Cataclysmic variables can experience short optical brightenings, which are commonly attributed to phenomena such as dwarf novae outbursts, micronovae, donor flares or magnetic gating bursts. Since these events exhibit similar observational characteristics, their identification has often been ambiguous. In particular, magnetic gating bursts and micronovae have been suggested as alternative interpretations of the same phenomena. Here we show that the timescales and energies separate the optical brightenings into separate clusters consistent with their different classifications. This suggest that micronovae and magnetic gating bursts are in fact separate phenomena. Based on our finding we develop diagnostic diagrams that can distinguish between these bursts/flares based on their properties. We demonstrate the effectiveness of this approach on observations of a newly identified intermediate polar, CTCV J0333-4451, which we classify as a magnetic gating system. CTCV J0333-4451 is the third high spin-to-orbital period ratio intermediate polar with magnetic gating, suggesting that these bursts are common among these rare systems.
