Star System With Right-Angled Planets Surprises Astronomers

 


Only recently, researchers have realized that on a small world, we might find those planets that have the right-angled planets where the earth is 200 million kilometres from them. There are four of those planets in the Star System 10110, which make up the best planetary system found to date, and scientists are wondering what these exoplanets are doing.

The four planets in question are located extremely close to each other - between them, they also form eight other planets which range in size from Earth to just a few light years away, even though they themselves are far from the Earth. These planets have a mutual orbit, and scientists say that scientists may discover future planets that can form the right-angled planets and that they are more likely to be more complex than they are right now, for example, if they are closer to each other in mass, which is likely to happen in the future. The planets have fewer than 100 times the surface area that Earth has, making it the closest planetary system to the Earth in terms of the number of planets on the surface. A couple of researchers from the Tohoku University said that all the planets in this system are very interesting, since they have not yet experienced a mass transfer.

"Our surprise was that these planets did not have a mass transfer, which we expected. So, this indicates that possibly once the planets formed in their current forms, they survived out in the parent system," said Fumiya Sugakawa, a cosmologist and a researcher at the University of Tokyo. Sugakawa's research group studied the interaction of a multitude of recent exoplanets that have been detected within the (birth) system, of which two were in the Star System 10110, along with a planetary system 41128. They found that five of the planets in the Star System 10110 were in the night sky in X-zero degrees, or around 0.012 deg, and the other three were in the morning sky, and the uprise of these planets was not steady but increased by the years. When the planets were distant from the mother planet, the scientists saw erratic movements in the orbit changes. As soon as the two planets were closer to each other, the researchers saw something different, suggesting that these planets could either have different orbits or create new planets.

"To be able to detect planets in the incubation process of their offspring is hard, but to detect planets before they are at least a few hundred million kilometres from the sun is much harder," said Dr Mitsuo Kato, a cosmologist from National Institute of Astronomy, Japan. Kato's research group confirmed that one of the two planets present in the Star System 10110 would orbit around a unique star. The second planet is extremely young, at the age of no more than a few billion years. As a result, the researchers of Star System 10110 is possible that this planet is still more like a newborn or the late life of the Sun.

Kato said that it would be interesting to see how these planets would evolve, but he agrees that there are still some mysteries to be revealed.
