Author Contributions R.S. analysed and interpreted the data from which the presence of the planet was inferred. R.S., S.S., R.J., J.-E.S., S.B., R.Ø., T.D.O., I.B., R.G., A. Bonanno., G.V., M.R., C.-W.C., E.L. and M.P. contributed to the large amount of observations and/or data reduction. A. Baran., S.C., N.D., S.K., D.K., P.M., R.R. and S.Z. contributed to the organization and/or on-line data reduction/analysis during the XCov23 Whole Earth Telescope campaign of August-September 2003, in which V 391 Peg was observed as a secondary target. S.K. performed some tests on theoretical . S.K. and S.Z. did independent checks of the O–C fits. E.L. made statistical tests on the significance level of the O–C fits. All authors discussed and interpreted the results and commented on the manuscript. D.K. and R.Ø. in particular helped to improve the text.
