UNLV researchers and collaborators have identified the first known planet orbiting three stars.
unlike us Solar SystemConsists of a single star, presumably half of all star systems, such as GW Ori, where astronomers have observed a new phenomenon, consisting of two or more stars which are attractively related to each other.
However, no planet orbiting three stars has been discovered – nor does one. Maybe now.
UNLV astronomers used observations from the Atacama Large Millimeter/Sub-Strong Array (ALMA) to analyze the three observed dust rings around the three stars important for production. planets.
However, they found a large but mysterious hole in the surrounding disk.
The research team investigated various origins, including the possibility that the gap was caused by the gravitational torque of three stars. But after building the comprehensive GW Urey model, they found that the presence of one or more massive Jupiter-like planets in nature was a more likely and attractive explanation for the disk’s location. Jeremy Smallwood, lead author and recent Ph.D. A bachelor’s degree in astronomy from UNLV is usually the first planet to form in a star system. It is followed by planets such as Earth and Mars.
The planet itself cannot be seen, but it was revealed – the study sheds light in September. Monthly announcement of the Royal Astronomical Society– Indicates that this is the first oceanic planet to be discovered. More observations from the ALMA telescope are expected in the coming months, which may provide direct evidence of this phenomenon.
“It’s really exciting because it makes the theory of planet formation really powerful,” Smallwood said. “It could mean that the planets are more active than we thought, which is a great thing.”
