RV and photometric observations of TOI-181. In all cases, the red curves are best-fit models, and the residuals are plotted beneath the data. The error bars include a white-noise jitter term added in quadrature. (a) PFS velocities spanning a transit and exhibiting the RM effect. (b) HARPS velocities across all orbital phases. (c) MOANA photometry of the same transit observed with PFS. (d) Phase-folded photometry based on TESS observations with 2-minute cadence (green). In panels (c) and (d), the darker points are time-averaged data. Data behind the figure are available electronically.
