Orbital solutions for Kepler-1625 b and its suspected exomoon based on the combined Kepler and Hubble data. Panels a–c: Kepler PDCSAP flux. Panel d: quadratic detrending of the Hubble data from Teachey & Kipping (2018). The blue curves show 1000 realizations of our PTMCMC fitting of a planet-moon model. Our most likely solution (red line) is very similar to the one found by Teachey & Kipping (2018), but differs significantly from the one initially found by Teachey et al. (2018). Panels e–g: Kepler PDCSAP flux. Panel h: our own detrending of the Hubble light curve (in parallel to the fitting). The ingress and egress of the model moon are denoted with arrows and labels in panel has an example.
