Compact hierarchical triple star candidates in and near the Northern Continuous Viewing Zone of TESS

There are thousands of previously known and newly identified eclipsing binaries observed almost continuously for nearly a year long during Year 2 of the TESS mission. These precise and unique data sets give us an opportunity to measure a significant amount of their eclipse times on a time-scale comparable to the usual outer orbital periods of compact hierarchical triple stellar systems (below 1-2 years). In our project, we obtain the light curves from TESS Full-Frame Images of more than 4,000 eclipsing binaries observed at least during 8 Sectors and determine their eclipse timing variations in order to search for the signals of third-body perturbations and/or light travel time effect caused by an unseen, more distant component. We present orbital solutions for the identified triple systems and statistical considerations will also be discussed.
