25 Mar 2019: According to Reichert et al. 2019: "Oscillatory convective modes might be a plausible alternative explanation of the observed radial-velocity variations."
20 Dec 2010: According to Hatzes 2008: "The most likely explanation for the 630-day RV variations is that they are due to a planetary companion." But the planet is still not published in a refereed Journal.
