Planets for Tau Ceti - maybe

[granthutchison]

Tuomi et al. Signals embedded in the radial velocity noise. Periodic variations in the tau Ceti velocities. (http://arxiv.org/abs/1212.4277)

It just appeared on arxiv yesterday, so it's highly provisional. But given the likely interest I've added the system to extrasolar.ssc on the SVN tree. (http://celestia.svn.sourceforge.net/viewvc/celestia/trunk/celestia/data/)
