我们创建了APOGEE-GALEX-Gaia星表来研究白矮星（WD）双星。该数据库旨在从GALEX、Gaia和APOGEE数据组合中创建一个最小偏差的WD双星系统样本，以增加具有轨道参数和化学成分的WD双星的数量。我们确定了3414个WD双星候选源，光谱类型在F和M之间的非简并伴星，包括主序星、主序星、亚巨星、亚巨星、红巨星和红团星。我们的研究结果包括：（a)与ce后（P < 100天）的WD二元候选者相比，共有1806个系统推断出WD半径为R 100天）。
We created the APOGEE-GALEX-Gaia catalog to study white dwarf (WD) binaries. This database aims to create a minimally biased sample of WD binary systems identified from a combination of GALEX, Gaia, and APOGEE data to increase the number of WD binaries with orbital parameters and chemical compositions. We identify 3414 sources as WD binary candidates, with nondegenerate companions of spectral types between F and M, including main-sequence stars, main-sequence binaries, subgiants, sub-subgiants, red giants, and red clump stars. Among our findings are (a) a total of 1806 systems having inferred WD radii R 100 days) compared to post-CE (P < 100 days) WD binary candidates.
