The claim from Dawson et al. (2010) is "We find that the period of 2.817 days reported in the literature for planet e (McArthur et al. 2004, Fischer et al. 2008) is actually a daily alias of its true period of 0.737 days. This new period of 0.737 days, with a refined mass of 10 Mearth, produces a significantly improved 5-planet Keplerian fit for 55 Cnc and is the shortest known period for a planet."

And the other star orbiting 55 Cancri.

55 Cnc B? That doesn't affect the system much.

This system has been updated for the 2.0.4 release.

I recreated the simulation using the data found here:
