Unlike our remarkably flat solar system, whose planets orbit all planes, the alien star-system GW Orionis, located only 1,200 light-years away in the constellation Orion, has three stars and a distorted, scattered and drawn disk. Rings tilted around them. Alexander Kreplin, an astronomer at the University of Exeter, says the first direct evidence that the three systems could tear their planet has been revealed. The formation of the disc, “This raises an exciting possibility: there may be an alien population of exoplanets orbiting their stars in very inclined and distant orbits.”
“Any planets formed in the wrong ring will orbit the star in a very diagonal orbit, and we predict that future planet imaging surveys will find many planets in a diagonal, wide-split orbit,” Kraplin added.
GW Orionis’ three-star system
To reach this conclusion, a team from the University of Exeter and Leicester observed the stellar system GW Orionis for more than 11 years and mapped the orbits of the stars with unprecedented accuracy. “We’ve found that all three stars don’t orbit in the same plane, but their orbits are incorrectly connected to each other and in terms of disks,” said team member Allison Young.
An international team of experts led by astronomers from the University of Exeter has identified GW Orionis, where observations with very large telescopes from the European Southern Observatory can be used to wrap dust and gas around multiple planets. (VLT), Georgia State University’s Center for High-Angular Resolution Astronomy Telescope Array (CAARA), and Atacama Large Millimeter / Submillimeter Array (ALMA).

Planets with spectacular views
The view of the potential planets around the system will give the observer a spectacular view of the tilted, multiple star constellations – similar to the Star Wars tattoo, says the University of Exeter team.
The research is the first output of a large program on a young stellar system, using a leading infrared imager called MIRC-X, which provides a new understanding of ga dust dust rotation, situational disks and how stars and planets are formed. The gas surrounding the young stars. The imager bait telescope connects light from all six telescopes in the arena.
“We are really excited that our new MIRC-X imager has given this interesting system a sharp look and revealed the gravitational dance of the three stars of the system. Normally, planets form around a flat disc of smoky dust and gas – yet our images reveal an extreme case where the disc is not flat at all, but is drawn and has a false ring that is broken from the disc, ”Stefan said. Krauss said the professor of astrophysics at the University of Exeter, who led the published research in science.
“Instead it is fitted and has the wrong ring that is broken from the disc. The misleading ring is located in the interior of the disc near the three stars. The effect is that the view of the potential planet inside this ring, like Star Wars fame, looks remarkable like a tattoo. “
The inner ring contains 30 dusty earth masses
The team inspected the system with the SPHERE instrument and ALMA on ESO’s VLT, and were able to create an image of the inner ring and confirm its misconceptions. The team watched the shadows as this ring lays on the rest of the disc. This helped them to create a 3D shaped figure of rings and overall disc geometry.

“We did simulations that showed that the disks around the three stars could be filled in different rings due to misunderstandings in their orbits. This is what we see in the observations. ”Said Matthew Bate, a professor of theoretical astrophysics at Exiter, who performed some computer simulations on the system. “The observed shape of the inner ring also matches the predictions on how the disc will rupture.”
The research, published in the journal Science, was presented in the paper, “The Triple Star System, which consists of a systolic disk shaped by misaligned and wrapped displays,” published in the journal Science.
