论文摘要
Gaia DR3为单层光谱二进制（SB1）提供> 181，000径向速度溶液，可通过选择具有较大质量功能的系统来搜索非相互作用的紧凑型对象+Star二进制候选。我们选择了234个这样的系统，并在DR3中确定了具有良好RV解决方案的114个系统。我们使用来自ASAS-SN和TESS的光曲线来识别和删除31个黯然失色的二进制文件，以产生80个紧凑型物体+星候选物的目录，包括38个椭圆形变量。这些候选人在GAIA和2MASS CMD上的位置表明，其中许多系统都是具有发光伴侣的二进制方法。我们比较了Gaia DR3和ASAS-SN中脱落的二进制文件的时期和偏心率，并发现约11％和约60％的二进制文件具有不同的时期和偏心率。我们还比较了Gaia DR3和光谱二进制轨道（SB9）中的311个二进制文件的RV溶液（SB9），并发现了相似的结果。我们没有确定任何强大的候选者，用于非相互作用的紧凑型物体+恒星二进制文件。
Gaia DR3 provides >181, 000 radial velocity solutions for single-lined spectroscopic binaries (SB1s) which can be used to search for non-interacting compact object+star binary candidates by selecting systems with large mass functions. We selected 234 such systems and identified 114 systems with good RV solutions in DR3. We used light curves from ASAS-SN and TESS to identify and remove 31 eclipsing binaries to produce a catalog of 80 compact object+star candidates, including 38 ellipsoidal variables. The positions of these candidates on Gaia and 2MASS CMDs suggest that many of these systems are binaries with luminous companions. We compared the periods and eccentricities of detached eclipsing binaries in Gaia DR3 and ASAS-SN, and found that ~11% and ~60% of the binaries had different periods and eccentricities. We also compared RV solutions for 311 binaries in both Gaia DR3 and the Ninth Catalog of Spectroscopic Binary Orbits (SB9), and found similar results. We do not identify any strong candidates for non-interacting compact object+star binaries.
