TESS and ESPRESSO phase-folded data of TOI-283 b. Panel a: TOI-283 b phase-folded TESS light curve after subtracting the photometric variations from the time series. The best-fit transit model is shown in black. The circles are TESS binned observations. Panel b: residuals of the transit fit. Panel c: ESPRESSO phase-folded RV measurements and best fit (blue line) after subtracting the quadratic trend and red-noise component. Panel d: residuals of the RV fit.
