“In the case of TOI-411, two planets were found by this first quick automated search. At the beginning of 2021, though, I was leading another project related to TESS, As Cacciupoti and his Planet Patrol indicated in a previous study , they also noticed a new signal in the lightcurve of TOI-411 that was a possible indication of a third planet. Ordinarily, astronomers would attempt to confirm a possible transit signal using the Radial Velocity method, where spectra is obtained from the parent star to determine its velocity back and forth . This is then used to calculate the gravitational forces acting on the star, which may result from a planetary system.
