amplitude and the HARPS and CORALIE uncertainties, we fully expected a large evidence ratio to confirm the nature of the signal. The signal is also clearly apparent in the MMSE periodogram as the strongest trough, adding to its reality.

We find a mass for the star of 1.02 , leading to a planetary minimum mass of 5.5 . This super-Jupiter also has appreciable eccentricity, at the level of 0.4, and the final Keplerian model to the phase folded velocities are shown in Fig. \[phased4\]. We note that the solution gives rise to a transit probability for this star of 1.6%, a relatively high likelihood of transit for such a planet-star separation.

HD128356
--------

HD128356 is the coolest star we have included in the CHEPS sample and is classed as a main sequence star by Hipparcos (K3V). We find the star to have a \[Fe/H\] of almost +0.2 dex, and with a $\Delta M_V$ of 0.55, it may be a subgiant star, or at least in the process of evolving onto the subgiant branch.

Using our Bayesian approach we detected a signal with a semi-amplitude of 37 and period approaching 300 days that had a log-Bayesian evidence ratio of 144.5. The
