Three-star extraterrestrial planet: In the investigation of an exoplanet in the universe, our researchers do not ignore any planet. They try to know the processes of origin of the Solar System from their study. In this way, a lot of information has been received about the methods of researchers. Astronomers also find many unique structures in this exercise. Usually, astronomers find such planets, which revolve around one or at most two stars. But researchers have come to know indirectly about an extraterrestrial planet that orbits not one but three stars (3 stars orbiting planet). This is said to be the first such discovery.
There is more number of such bound stars
The strange thing about this system is that where planets orbiting two stars are rarely found. This planet is orbiting three stars. This discovery has been made by University of Nevada researchers and their colleagues in Las Vegas, USA. It is believed that half of the all-star systems are systems in which two or more stars are gravitationally bound.
No star is born alone
It is generally believed that all the stars in the universe were born at least as a double star system and that the star seen today alone was once separated from its companion star. There is also this belief about our Sun that it has separated from its partner. But even after this, no such planet could be discovered which was revolving around three stars.
Observation from alma
The researchers used observations from the powerful Atacama Large Millimeter/submillimeter Array (ALMA) telescope to analyze the three dust rings of these stars that play a crucial role in planet formation. Nevertheless, he noticed a significant but strange difference in all three circumtriple discs.
This strange celestial body has been called GW Ori. It also has a disc that is divided into two parts at oddly 38-degree angles. It looks like the disk of Saturn, which has broken and crooked in the middle. This planet is located 1300 light-years away from Earth, which is strangely orbiting three stars. Inside this disk, there is about 30 times more material than Earth, enough for the formation of planets.
Signs of the presence of a giant gaseous planet
The team of researchers investigated different origins, in which the possibility was also explored whether the gap that came between the three stars was not a gravitational torque. After modelling GW Ori, the researchers found that a more accurate explanation of the size and position of this disk is the presence of one or more Jupiter-like planets.
Such planets are formed first
According to UNLV’s PhD graduate and lead author of this study, Jeremy Smallwood, giant gaseous planets are the first to form in a star system. After this, again rocky planets like Earth and Mars are formed. This planet has not been seen directly, but its investigation has been told in research published in Monthly Notices of the Royal Astronomical Society in September. In which it is the first circumtriple ever discovered, that is, a planet orbiting three stars.
More data from the ALMA telescope observations are due in the coming months, which is expected to provide direct evidence of this phenomenon. Smallwood says that this is really interesting because this investigation is only strengthening the theory of planet formation. This clearly means that the process of planet formation is much more active than we have been understanding.
