Discover 9 new planets

The discovery of nine exoplanets has challenged current theories about the formation of planets, according to new observations by astronomers. Two of the astronomers involved in the discovery work at the Global Telescope Network of the University of California's Las Cumbres Observatory (LCOGT).

Unlike the planets in our solar system, two of the newly discovered planets turn in the opposite direction to the direction of their host star (host star). It is this strange thing that forces scientists to come up with a new theory to explain how planets are made.

Other similar findings were presented at the National Astronomical Conference meeting in Glasglow, Scotland. This is the first time to announce the new planets before posting in the Professional Journal.

Tim Lister, an LCOGT project scientist, said: "The theorists about how to evolve planets before the task must explain how much of the planets have been put into orbit." Lister is leading a major part of the observation with Rachel Street of LCOGT, Andrew Cameron of Andrews University in Scotland and Didier Queloz of the Swiss Astronomical Observatory in Geneva.

The data collected by LCOGT is the basis for confirming new planets. With the addition of these nine "transition" planets, the number of transitional planets increased from 81 to 90. Transitions occur when an object passes in front of the host star and blocks part of the light. of this star, like eclipse, slightly reduces the brightness of the host star and hence can infer the mass, diameter, density and temperature of the transition planet.

According to the initial discovery of the new exoplanets of 'Wide Angle Search' (Wide Angle Search for Planet, WASP) project, the team of astronomers combined data obtained from the telescope. The LCOGT's 2-meter diameter is located in Hawaii and Australia, along with other telescopes, which on this basis confirms this discovery and finds their characteristics.

9 planets are called 'Hot Jupiter'. They are giant gaseous planets in orbit close to their host stars. In the 15 years since the discovery of the first 'hot Jupiter', their origins are a big question for astronomy. Because they are both large and close, they are easily detected by the gravitational impact on their stars.

The core of the giant planets is thought to form due to the mixing of rock particles (ice) and ice only found in the outer, cold regions of the planetary system. Therefore, "Hot Jupiter" must form far away from their stars and move inwardly, pulling for several million years. According to many astronomers, this happens due to the gravitational interaction with the disk and then forming rocky planets like Earth. However, the new results suggest that it is not so simple, because if that is the case, it is not possible to explain why the planets, when entering orbit in the opposite direction of the dust disk.

According to the team, the most logical shifting hypothesis is the proximity of 'Hot Jupiters' to their stars not because of the interaction with dust disks in general, but rather slowly evolution in a game. tug-of-war with other planets or stars for hundreds of millions of years. Overwhelmed on trajectories that cause them to tilt and relax, this giant wandering gas is always subjected to friction, it is pushed close to the host star, and at some point falls into the fund. The religion is almost round, but it is tilted close to the star.

Rachel Street - LCOGT's project manager - concluded: "In this scenario, smaller planets on orbits similar to Earth's orbit are hard to survive."
