Planet-forming Lifeline Discovered in a Binary Star System

For the first time, researchers using ALMA have detected a streamer of gas flowing from a massive outer disc toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disc of planet-forming material that otherwise would have disappeared long ago. Half of Sun-like stars are born in binary systems, meaning that these findings will have major consequences for the hunt for exoplanets. The results are published in the journal Nature on 30 October 2014

Since GG Tau Ab is itself a binary star (GG Tau Ab1, Ab2), that's a circumtriple disc, in a quintuple system (GG Tau B is a low-mass binary with Bb being substellar)
