By observing our solar system, astronomers have gained an idea of how planets formed. So they believed that the giant planets should rest on a relatively massive solid core. Did they think … because observations made on an exoplanet called Wasp-107b now raise this conclusion into question.
In 2019, researchers announced that they had discovered . Today, one of those researchers, Caroline Biaulit, (Canada), reveals amazing works related to another : Wasp-107b. La From his heart he would be much weaker than society thinks.
Remember that Wasp-107b is an atypical planet. It was discovered in 2017, about 212 . And for him He is also close to it Sixteen times more than ours . It is touring at 5.7 at present only. So much so that she finds it difficult to hold it .From our land, in . She is almost the same length , But its mass is much less. Wasp-107b is what call up
Thanks to the data obtained in (Hawaii), researchers at the University of Montreal were able to measure accuracy Its host star wobbled due to the gravitational force of Wasp-107b. Thus, they established its mass at about one-tenth of the mass of Jupiter.
Hubble has been used to detect helium in the atmosphere for the first time ever in a world outside our solar system! The WASP-107b exoplanet is one of the least dense planets known. While it is roughly the size of Jupiter, it contains only 12% of Jupiter’s mass: https://t.co/9ngmXQdfeWpic.twitter.com/S8BPXdMHUr

An incredibly bulky core
Then astronomers conducted an analysis to determine the planet’s internal structure. Their conclusion: Mass Wasp-107b should not exceed four times the Earth. Thus, more than 85% of the planet’s mass lies in the thick layer of Around this kernel. Amazing thing. Because you must know that For example – whose mass is close to Wasp-107b’s mass – it accounts for no more than 15% of its mass in this gas layer.
Until now, researchers believed that a relatively massive nucleus was necessary for formation . A condition without which the planet cannot hold a large number of gas layers. But this discovery related to Wasp-107b indicates that They form much more easily than astronomers thought. This in particular could have formed some distance from its star – where the gas is cool enough to smooth out – Before moving to its current position.
Other questions still unanswered about the Wasp-107b. The atmosphere for this type of planet, for example, must be rich in methane. However, the reviews, Which was implemented in 2018, appears to show the opposite. The researchers now plan to re-analyze these findings in light of their new findings regarding the overall distribution of exoplanets. And maybe know the mechanism that could explain such destruction of methane.
