论文摘要
可变来源探测广泛的天体物理现象。我们提出了一个超过一千万个可变源候选的目录，该目录在Zwicky Transient设施（ZTF）的数据版本1（DR1）中发现。我们进行周期性搜索，最高为160天^-1，然后将光曲线分类为不稳定和光滑的变量。我们还提出了可变性指标和在ZTF-DR1 Light Curve数据库中约10亿个来源的周期性搜索的结果，最高为5天^-1的频率。我们介绍了几个新的短期（<90分钟）候选人，以及大约60个新的矮人Nova候选人，包括两个候选人黯然失色的系统。 1000万个变量目录和约10亿个源目录都以CATSHTM格式在线获得。
Variable sources probe a wide range of astrophysical phenomena. We present a catalog of over ten million variable source candidates found in Data Release 1 (DR1) of the Zwicky Transient Facility (ZTF). We perform a periodicity search up to a frequency of 160 day^-1, and we classify the light curves into erratic and smooth variables. We also present variability indicators and the results of a periodicity search, up to a frequency of 5 day^-1, for about 1 billion sources in the ZTF-DR1 light curve database. We present several new short-period (<90 min) candidates, and about 60 new dwarf nova candidates, including two candidate eclipsing systems. Both the 10 million variables catalog and ~1 billion source catalog are available online in catsHTM format.
