AE Aqr objects are a class of cataclysmic variable stars in which the rapidly rotating magnetosphere of the white dwarf (WD) primary centrifugally expels most infalling gas before it can accrete onto the WD. The expulsion of the accretion flow via this “magnetic propeller” extracts angular momentum from the WD and produces large-amplitude, aperiodic flares in optical photometry. The eponymous AE Aqr is the only confirmed member of this class of object, but recently, Thorstensen discovered a candidate AE Aqr system: LAMOST J024048.51+195226.9. Using survey photometry, we measure a refined orbital period for this system and identify a shallow, previously unrecognized eclipse during which the system’s frequent AE Aqr-like flaring episodes cease. A dedicated follow-up study is still necessary to test the proposed AE Aqr classification for LAMOST J024048.51+195226.9, but should it be confirmed, the eclipse of its flare-production region will offer a new means of studying the magnetic...

LAMOST J024048.51 + 195226.9（候选AE Aqr型大灾变星）中的轨道食的识别

AE Aqr天体是一类灾难性变星，其中白矮星（WD）的快速旋转的磁层主要通过离心作用将大多数落入的气体排出，然后才能积聚到WD上。经由此“电磁推进器”排出的积聚流从WD提取角动量，并在光学测光法中产生大幅度的非周期性耀斑。同名AE Aqr是此类对象中唯一被确认的成员，但是最近，Thorstensen发现了候选AE Aqr系统：LAMOST J024048.51 + 195226.9。使用调查光度法，我们测量了该系统的精确轨道周期，并确定了一个较浅的，以前无法识别的日食，在此期间系统频繁出现类似于AE Aqr的爆发事件。
