Abstract

In this work, I report that large fraction of stars detected by A A, 674, A170 2023A&A...674A.170A and noted in that work as new discoveries are in fact known systems. This is especially true for the dense bulge fields with large blending of nearby sources. Among the published 245 stars determined to be doubly eclipsing (i.e. containing two eclipsing signals), I identified 53 blends. In other words, about a quarter of the systems noted by 2023A&A...674A.170A are not actually doubly eclipsing; rather, these are contaminations of known nearby sources that have already been detected by OGLE. Such a high proportion of reported false positives should not be readily ignored and ought to be addressed in future studies.
对 Ádám 等人(2023)的评论 :报告了大量已知系统
在这项工作中,我报告说A A、674、A170 2023A&A......674A.170A探测到的大部分恒星实际上是已知系统。在已发表的被确定为双食星(即包含两个食信号)的245颗恒星中,我发现了53颗混合星。换句话说,2023A&A......674A......170A所指出的系统中,大约有四分之一实际上并不是双食系统;相反,这些都是已经被OGLE探测到的已知附近来源的混合。报告的假阳性比例如此之高,不应轻易忽视,并应在今后的研究中加以解决。
