Photometric brightness variations have been found with the same period as the supposed stellar velocity variations, implying that the velocity variations are caused by starspots, not by a planet; see A False Planet Around HD 192263 (G.Henry, S.Baliunas, R.Donahue)
Additional observations indicate that the radial-velocity variations are indeed being produced by the presence of a planet; see The return of the giant planet orbiting HD192263
1 AU = 1.49597870691·1011 m            1 year = 365.25 days = 31557600 s            1 ME = 5.9742·1024 kg
