Pulsar binaries, in particular redback systems, provide good sources to study the pulsar wind flow and its interaction with the companion stars. Fermi-LAT have proposed probable pulsar binary candidates in its catalogs. An orbital modulation search of binary candidates is an effective way to identify pulsar binary sources from the catalog. Transiting Exoplanet Survey Satellite (TESS) observes in survey mode for a large part of the sky and thus provides an excellent data set for the 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 n...

使用TESS周期性搜索脉冲星二进制

脉冲星双星，特别是红背系统，提供了研究脉冲星风流及其与伴星相互作用的良好来源。Fermi-LAT已在其目录中提出了可能的脉冲星二元候选物。二进制候选者的轨道调制搜索是从目录中识别脉冲星二进制源的有效方法。过渡系外行星勘测卫星（TESS）在勘测模式下对大部分天空进行观测，因此通过观测通量变化（据认为主要来自恒星伴星）为脉冲星双星候选者的周期性搜索提供了一个极好的数据集。使用TESS数据，我们寻找具有报告的轨道周期的五个脉冲星双星（或候选星）的通量调制，包括PSR J1023 + 0038、3FGL J0523.3-2528、3FGL J0212.1 + 5320、3FGL J0744.1-2523和PSR J1417−4402，证明TESS光度数据对于识别类似Redback的系统的周期性非常有用。此方法可以有效地搜索n ...
