论文摘要
我们基于Gaia DR3搜索二进制文件中的紧凑对象。在条件下得出了十个目标的样本：径向速度变量，低温（$ t _ {\ rm eff} <6000 $ k），高质量功能（$ f（m_2）> 1 m_ \ odot $）和椭圆形的类似光曲线。两个靶标具有杆光谱观测，其中一个是双线光谱二进制的。七个目标的观察数据不是自洽的，因为它们的光度测定周期还短于Gaia DR3的恒星参数计算出的理论最小轨道周期。在排除了这七个不一致的目标和另一个近光星污染的目标之后，其余两个目标可能包含值得跟进的紧凑对象。这项工作可以作为证明在大量Gaia数据中搜索紧凑对象的可行性的一个例子。
We search for compact objects in binaries based on Gaia DR3. A sample of ten targets is derived under the conditions: radial velocity variable, low temperature ($T_{\rm eff} < 6000$ K), high mass function ($f(M_2) > 1 M_\odot$), and ellipsoidal-like light curves. Two targets have LAMOST spectroscopic observations, one of which is a double-lined spectroscopic binary. The observational data of seven targets are not self-consistent, since their photometric periods are even shorter than the theoretical minimum orbital periods calculated by the stellar parameters from Gaia DR3. After excluding these seven inconsistent targets and another target contaminated by a near-bright star, the remaining two targets may contain compact objects worth follow-up observations. This work may serve as an example to demonstrate the feasibility of searching for compact objects in the massive Gaia data.
