论文摘要
将$ g $ bant的幅度$ <17 $和3.33 $> 3.33的三角镜头视差$> 3.33 $ milli-arcseconds交叉匹配到过境外部外部调查高级科学产品和全框图像以提取可能的白色dwarf变量的光线以提取出可能的白色曲线。在至少27天的观察周期中观察到样品中的大多数目标，并具有30分钟的节奏。基于由衰减光曲线构建的lomb-scargle周期图，有600多个来源表明了周期性的可变性。本文提出了识别的早期结果。
A sample of 4 thousands Gaia sources with apparent $G$-band magnitudes of $<17$ and trigonometric parallaxes of $>3.33$ milli-arcseconds were cross-matched to the Transiting Exoplanet Survey high level science products and the Full-Frame Images in order to extract the light curves of possible white dwarf variables. Most of the targets in the sample were observed in at least 27-day observing cycle with 30-minutes cadence. Based on Lomb-Scargle periodogram constructed from de-trended light curves, more than 600 sources have indication of periodic variability. This paper presents the early results from the identification.
