OU-Led Team Discovers Rare, Newborn Tri-Star System

A rare triple-star system surrounded by a disk with a spiral structure has been discovered by a University of Oklahoma-led research team. Recent observations from the Atacama Large Millimeter/submillimeter Array — a revolutionary observatory in northern Chile, commonly known as ALMA — resulted in the discovery, lending support for evidence of disk fragmentation — a process leading to the formation of young binary and multiple star systems. Until ALMA, no one had observed a tri-star system forming in a disk like the one discovered by the OU team.
