论文摘要
Pulsar二进制组，尤其是红带系统，提供了良好的来源，以研究脉冲星风流及其与伴侣恒星的相互作用。 {\ it fermi} -lat在其目录中提出了可能的Pulsar二进制候选者。为了从目录中识别脉冲星二进制来源，对二进制候选者的轨道调制搜索是一种有效方法。 TESS在大部分天空的调查模式下观察，因此通过观察磁通变化（主要来自恒星伴侣），为Pulsar二进制候选者的周期性搜索提供了出色的数据集。使用TESS数据，我们查找具有报告轨道周期的五个Pulsar二进制文件（或候选）的通量调节，包括PSR J1023+0038，3FGL J0523.3-2528，3FGL J0212.1识别类似红色的系统的周期性。此方法可以有效地搜索新的Pulsar二进制文件或类似的二进制系统。
Pulsar binaries, in particular redback systems, provide good sources to study the pulsar wind flow and its interaction with the companion stars. {\it Fermi}-LAT have proposed probable pulsar binary candidates in its catalogs. To identify pulsar binary sources from the catalog, orbital modulation search of binary candidates is an effective way. TESS observes in survey mode for a large part of the sky and thus provide an excellent data set to periodicity search of pulsar binary candidates by observing the flux variation, thought to mainly come from the stellar companion. Using TESS data we look for flux modulation of five pulsar binaries (or candidates) with reported orbital periods, including PSR J1023+0038, 3FGL J0523.3-2528, 3FGL J0212.1+5320, 3FGL J0744.1-2523 and PSR J1417-4402, demonstrating that TESS photometric data are very useful in identifying periodicities of redback-like systems. This method can be effective in searches for new pulsar binaries or similar binary systems in the future.
