TTV measurements of TOI-1232 b modeled simultaneously with the RVs of TOI-1232 from FEROS using a two-planet dynamical model. The top panel presents the TTV time series around a mean (osculating) period of P = 14.25503 days, alongside a model consistent with two massive planets near the 2:1 MMR. The bottom panel displays the residuals of the TTVs after subtracting the best-fit model.
