Oct 26, 2016 - OU-Led Team Discovers Rare, Newborn Tri-Star System

Prof. John J. Tobin led a global team of researchers who discovered a rare triple star system surrounded by a disk with a spiral structure.  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.
