论文摘要
我们对新的灾难性变量星（CVS）进行光度搜索，目的是确定Ar〜scorpii-type二进制系统的候选物。我们选择可能与未识别的X射线源相关的GAIA来源，并分析台湾的Zwicky瞬态设施，过渡系外行星调查卫星和Lulin One米望远镜所采取的光曲线。我们研究了八个来源作为简历的候选者，其中六个来源是新的标识。在先前的研究中，另外两个来源被认为是CVS，但尚未进行详细的研究。我们确定了两个与身份不明的XMM-Newton或Swift Source相关的黯然失色的系统，以及一个与未知的AskA源相关的极性候选人。两个极地候选者可能会位于简历的所谓周期间隙，而其他六个候选者的轨道周期比周期间隙短。尽管我们没有确定AR〜Scorpii-Type二进制系统的有前途的候选人，但我们的研究表明，在先前的调查中可能会错过X射线发射并且没有显示出频繁爆发的CV系统。
We carry out a photometric search for new cataclysmic variable stars (CVs), with the goal of identification for candidates of AR~Scorpii-type binary systems. We select GAIA sources that are likely associated with unidentified X-ray sources, and analyze the light curves taken by the Zwicky Transient Facility, Transiting Exoplanet Survey Satellite, and Lulin One-meter Telescope in Taiwan. We investigate eight sources as candidates for CVs, among which six sources are new identifications. Another two sources have been recognized as CVs in previous studies, but no detailed investigations have been done. We identify two eclipsing systems that are associated with an unidentified XMM-Newton or Swift source, and one promising candidate for polar associated with an unidentified ASKA source. Two polar candidates may locate in the so-called period gap of a CV, and the other six candidates have an orbital period shorter than that of the period gap. Although we do not identify a promising candidate for AR~Scorpii-type binary systems, our study suggests that CV systems that have X-ray emission and do not show frequent outbursts may have been missed in previous surveys.
