A Jupiter-sized world may be kicking up dust in the triple-star system GW Ori.

There's now even more evidence that a bizarre star system perched on the constellation Orion's nose may contain the rarest type of planet in the known universe: a single world orbiting three suns simultaneously.

The star system, known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, makes a tempting target for study; with three dusty, orange rings nested inside one another, the system literally looks like a giant bull's-eye in the sky. At the center of that bull's-eye live three stars — two locked in a tight binary orbit with each other, and a third swirling widely around the other two.

Triple-star systems are rare in the cosmos, but GW Ori gets even weirder the closer astronomers look. In a 2020 paper published in The Astrophysical Journal Letters, researchers took a close look at GW Ori with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile, and discovered that the system's three dust rings are actually misaligned with one another, with the innermost ring wobbling wildly in its orbit.

The team proposed that a young planet, or the makings of one, could be throwing off the gravitational balance of GW Ori's intricate triple-ring arrangement. If the detection is confirmed, it would be the first triple-sun planet (or "circumtriple" planet ) in the known universe. Eat your heart out, Tatooine!

Now, a paper published Sept. 17 in the journal Monthly Notices of the Royal Astronomical Society offers fresh evidence of that rare planet's existence. The study authors conducted 3D simulations to model how the mysterious gaps in the star system's rings could have formed, based on observations of other dust rings (or "protoplanetary disks") elsewhere in the universe.

The team tested two hypotheses: Either the break in GW Ori's rings formed from the torque applied by the three twirling stars at the system's center, or the break appeared when a planet formed within one of the rings.

The researchers concluded that there is not enough turbulence in the rings for the stellar torque theory to work. Rather, the models suggest that the presence of an enormous, Jupiter-size planet — or perhaps several planets — is the likelier explanation for the rings' strange shape and behavior.
