I found a report about this on Physorg and wandered over here to share it, so FWIW:

The Sciencedaily article's better though.
What's most astonishing however is the sheer size of the resulting ternary system - from our perspective here on Earth, a full 26 LY away, Formalhaut C lies 5.5 degrees away from its primary - the span of eleven full moons...! A whopping 158,000 AU, or 2.5 light years!
Alpha Centauri / Proxima were a memorably massive system at 15,000 AU apart in FE2/FFE (0.2LY), but 158,000 AU is just off the scales of what we're used to considering as a distinct system, and throws open the possibility of ever larger ones, i suppose...
And if it's to be modeled properly in in E: D then i guess interstellar flight will have to be very much sur la table.. which augurs well..!
