Fig. 14.


Orbital fit of J2308−46. Upper panel: R-band transit obtained from the SAAO 1-m telescope (black) with the best fitting transit model (green dashed). We plot the best fitting transit model generated using Gaussian processes (red). Middle panel: phase-folded WASP observations (black) and observations binned into groups of 50 (blue). We also plot the Roche model used to approximate the out-of-transit photometry used to measure transit parameters from WASP photometry (red). Lower panel: drift-corrected radial velocity measurements (black) with the best fitting model (red) and residuals from the best fitting orbital model.
