Scientists have discovered a “forbidden” planet

Scientists have found a planet similar to Jupiter, but with a “forbidden” earth 4 times larger.

The planet has a large gas giant planet, similar to our Jupiter. However, its star is a red dwarf, only 4 times the size of Jupiter.

Previously, scientists thought it unlikely that such a small star could host such a large gaseous planet.

Shubham Kanodia of the Carnegie Institute of Science, who led the study, said: “It is extremely surprising that the parent star TOI-5205 formed a planet the size of Jupiter, only 4 times the size of Jupiter, but somehow the size of Jupiter. Jupiter!” says.

Gas giants used to form around such M-type dwarf stars. But the newly discovered star is younger and less massive.

Scientists have named the planet TOI 5205b after the star it orbits. “The presence of TOI-5205b deepens our knowledge of the disks from which these planets were born,” Kanodia says:

If initially there was not enough rocky material in the disk to form the first core, then the gas giant planet could not have formed. And in the end, if the disk evaporates before a massive core is formed, the gas giant will not be able to form. However, TOI-5205b emerged in spite of these barriers. According to our current nominal understanding of planetary formation, TOI-5205b should not exist; it is a “forbidden” planet.

TOI 5205b was first discovered as a possible planet by NASA’s Transition Exoplanet Survey Satellite, TESS. TESS is looking for signs of a diminution of light, known as a “transition,” which occurs when planets pass in front of their stars. TOI 5205b was notable for the relatively similar sizes of the planet and star. This means that it blocks about 7 percent of the light and is one of the largest crossovers known.

Later, scientists studying it with more telescopes confirmed that it was a planet whose size was considered impossible.

Researchers now hope to continue exploring this world with NASA’s recently launched James Webb Space Telescope. The fact that the transition is so large means that these observations will be especially fruitful and shed light on its composition, as well as on the unusual history of its birth.
