Searching for CoRoT-TESS triple stellar candidates

We report the first result of a search for CoRoT eclipsing binaries (EBs), which eclipse timing variation (ETV) shows the sign of potential light-travel time effect. To reveal their true nature, we needed longer time scales, thus we complement the CoRoT data with TESS measurements. Of about 2300 EBs, we focus our investigation on those systems, which were observed more than once both by CoRoT and TESS (in sectors 6 and 33), separately. We recalculate all of the orbital periods using phase dispersion minimization method, then produce the O-C diagrams. Finally, we analyze those systems in details that show sinusoidal ETVs with Markov chain Monte Carlo method. Here we present the analysis of a new hierarchical triple stellar system candidate.
