Stacked periodograms (left panel) and phase-folded (right panel, top plot) filtered RVs of IRAS 04125+2902. The stacked periodogram (with colors coding periodogram power) shows a marginal signal at the orbital period that strengthens as RV points are added to the analysis. In the right panel, the black stars show the RVs averaged over phase bins of 10%, with the phase-folded residuals displayed in the bottom plot.
