Planet-forming disks with misaligned rings discovered in multi-star system

Planet-forming disks with misaligned rings discovered in multi-star system

Science
Sept. 3 (UPI) -- Astronomers have discovered misaligned rings within the planet-forming disk surrounding a faraway, triple-star system, according to a study published Thursday in the journal Science. Scientists suspect the disk was disrupted by the gravitational pull from one of the three stars. Advertisement The trio of stars that form GW Orionis are located approximately 1,300 light-years from Earth. The system is noted for its giant protoplanetary disk. Recently, astronomers were able to confirm the disk's misalignment using observations by the Atacama Large Millimeter/submillimeter Array, a powerful observatory in Chile. By studying how the massive planet-forming disk came to be misaligned, researchers hope to better understand how planets around multi-star systems form and evolve. "...
