A Giant Planet and a Small Star Are Shaking Up Conventional Cosmological Theory

Many The stars Milky Galaxy is small, dark Red Dwarfs-Stars are smaller sun both in size and mass. Toi-6894 is one of them far away from the ground.

Astronomers thought such a star could not be the big planets of such a star, because the mass could not have only 20 percent of the sun, that is, there could be enough mass to form a huge body from the stars around the star Saturn or Round.

However, when adheres to TOI-6894, an international investigation team revealed a temporary reduction in a star’s glow of a star’s brightness. This is a newly discovered planet called Toi-6894B, 17 percent of the star’s light, the planet is very large. Selected by the signal The Exoplanet Survey Satellite has passed (TESS), an observation instrument launched Nasa Hunt to hunt for planets outside our solar system.

This TOI-6894 “The lowest mass star known to host such a planet” said Edward Bryant, At Astrofika University at the University of Astrophysics Award press. The findings carry out the usual theory of how the planets are built. “This discovery will be a cornerstone to understand that the structure of the huge planet is extreme,” he said.

Astronomers at the University College, University of London and Warwick, Chile, US and European partners, a global cooperation with the partners, the TOI-6894B watched the data of the 91,000 red dwarfs before discovering the planet. Was then the toi-6894b character clarified with additional observations made with other telescopes. According to them, the radius of TOI-6894B is slightly large, but its mass is only half of the alarm giant. Its density shows that it is an extremely light, expanding gas planet in 0.33 G / SM.

Toi-6894, this size is 40 percent less than the previous record of the smallest star with a planet. This fact creates a serious contradiction to the usual theories of the planet.

Model of the formation of a widely accepted planet “Core-collection theory,“The forms of protoplanetar discs around a star and the materials in this disk offer a combination of dust and rocks. But if the masses of larger gas are small, the mass of its protopanetar will be small. A giant gas planet will not increase.

According to this theory, it is estimated that a 120-fold substance is required from the ground to form the TOI-6894B. However, the star toi-6894 is only 58 times more than the mass of the most space in the observed disk. This increases the existence of an alternative planet formation mechanism.
