论文摘要
我们介绍了在苔丝周期14和15期间积聚白矮人Ex dra中的日食的研究。在此数据集中存在的两个爆发期间，eclips eclips eclips eclips eclips eclips eclips eclips eclips eclips the eclipsetic loop eclipse loop in Eclipse-depepth/of-Enfepth/ever-Enceplipse-flux-flux空间。在每种情况下，执行环的方向都会强烈表明爆发爆发，该爆发在积聚盘的内边缘附近触发并向外传播。反过来，这表明前DRA中的爆发是“内而外”的爆发。以前对矮新星磁盘的流体动力学研究预测的事件，并在许多其他积聚的白矮人系统中进行了光谱的确认。因此，我们建议将在日食深度/放下外的通量空间中执行的循环方向用作现象学上的测试，从而在其他黯淡的矮人novae中在现象学上区分“内部外”和“外部”爆发。可靠且纯粹的光度测试可区分这些现象。
We present a study of the eclipses in the accreting white dwarf EX Dra during TESS Cycles 14 and 15. During both of the two outbursts present in this dataset, the eclipses undergo a hysteretic loop in eclipse-depth/out-of-eclipse-flux space. In each case, the direction in which the loops are executed strongly suggests an outburst which is triggered near the inner edge of the accretion disk and propagates outwards. This in turn suggests that the outbursts in EX Dra are 'Inside Out' outbursts; events predicted by previous hydrodynamic studies of dwarf nova accretion disks and confirmed spectroscopically in a number of other accreting white dwarf systems. We therefore propose that the direction of the loop executed in eclipse-depth/out-of-eclipse flux space be used as a test to phenomenologically distinguish between 'inside out' and 'outside in' outbursts in other eclipsing dwarf novae; a reliable and purely photometric test to differentiate between these phenomena.
