(full paper can be found at: http://arxiv.org/abs/astro-ph/0309256 )

There's a table at the end of the paper (top of page 6) with the physical stats- apparently they're 1500 AU from Epsilon Indi, and the pair are separated by 2.65 AU.

Anyone fancy drawing that up in Celestia? ;)

Great discovery :D

Binary systems are great when we need to determine masses for those bodies. And when mass is known, many other physical properties can be deduced.

I've revised the definition for Eps Ind B in my NearbyStars add-on, to include Eps Ind Bb in a 16-year orbit. (Unfortunately, since Celestia doesn't support barycentres in stellar locations, I can't put the two components in mutual orbit.)
