This could be the first planet to hit a 3-star orbit

“The Star Wars movie got away with the trick,” said Rebecca Nealon of the University of Warwick in England, a co-author on the research.

Scientists are looking for a planet orbiting three stars and have found possible clues in another system, gg tau aIt is located about 450 light-years from Earth. However, scientists claim that the difference in gas and dust rings in GW Ori is a more compelling example.

“This may be the first evidence of a polar ocean planet creating a real-time hiatus,” said lead researcher Jeremy Smallwood of the University of Nevada in Las Vegas.

The scientists “make a good case,” said William Welch, an astronomer at San Diego State University. If it turns out to be a planet, it will be very cool.”

Alison Young of the University of Leicester in England, who has claimed that the holes in the system’s disk rather than the planet are caused by GW Uri stars, notes that observations from the ALMA telescope and the Very Large Telescope in Chile will be available in the coming months. You may end the discussion. .

“We will be able to look for direct evidence of a planet on a disk,” Dr. Young said.

If the planetary hypothesis is confirmed, the system will reinforce the idea that planetary formation is common. Many worlds, known as planets orbiting a planet, are actually known to orbit two stars at the same time. However, perihelion planets were hard to find – despite estimates at least a tenth A group of all stars in a system of three or more. However, their possible presence suggests that planets are exploding in all kinds of places, even in this most exotic system.

Dr. says. Nilon said.

This indicates that exoplanets are likely to form in increasingly unusual locations. “We knew that planets can form at any time, but they can,” said Shaun Raymond, an astronomer at Bordeaux University in France, who was not involved in the conference.
