I've read it...big problem with it....the mass and the radius don't jibe with the stellar theory...1.03M and 1.15R for a G8 star...hmmmm....that's more like a star of G1. However the anomalous spectral type is most likely due to the high metals content of the star.

The star is about 0.89L which is 167% brighter than it should be (should be 0.53L for a normal G8 star of its age and temp etc), given the latest references. If that star didn't have such a high metal content, its surface temp would be around 5900-5950K and the star would be just over 1.4L, which is pretty much bang on for a G1 star.
