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

Many They Milky Way Galaxy is small, faded Red dwarf– Stars are much smaller than this Sunshine Both in size and mass. Toi-6894, located far away from the earth, is one of them.

Astronomers previously thought that a stars like this could not promote it, because its masses are about 20 percent of the sun, which means its planetary system – generated from the stars’ materials – it could not contain enough mass Saturn Or JupiterThe

However, while observing the Toi-6894, an international research team has detected a clean transit signal-it is a temporary decrease in the stars as it crosses a planet. This newly discovered planet, known as Toi-6894b, blocks 17 percent of the stars, which indicates that the planet is fairly large. Was taken by the signalty Exoplanet Survey Satellite Transigating (Tess), an observation materials that were turned on by Nasal Out of our solar system, the planets are hunting for the stars.

It made the Toi-6894 “Hosting this planet today, the lowest ganma star,” Edward Bryant says, “Edward Bryant, a colleague of the University of Warwick, a colleague of the University of Warwick, A. Press statementThe The planets seem to encourage the conventional theory about how it is formed. “This discovery will be a basis for the final understanding of the formation of the giant planet,” Bryant said.

Astronomers at the University College London and Warwick University, as part of global cooperation with partners in Chile, Chile, the United States and Europe, trolled by TESS through the data of about 91,000 red dwarf stars before discovering the to-6894b planet. After that, the nature of the toi-6894b Clear by excess observation Made with other telescopes. According to them, the radius of Toi-6894b is a bit larger than Saturn, but its mass is about half than the ringed monster. Its concentration is extremely light in only 0.33 g/cm, it indicates that it is an expanded gas planet.

Toi-6894 is about 40 percent smaller than the previous record for the smallest stars with this size planet. This fact creates a serious conflict with the conventional theories of the planet formation.

Model for the formation of the widely recognized planet, “The theory of the original-handedness,“It suggests that a ring of dust and rocks known as the protoplanetary disk is made around a star, and those materials on this disc then combine to form the core of the planets.

Based on this theory, it is estimated that the substance is 120 times stronger than the earth will need to form a toi-6894b. However, the observation of the Star TOI -6894 has only 58 times the mass of the earth on the most earth mass. It enhances the possibility of the existing alternative planet-building process.
