By observing our solar system, astronomers understood how planets are formed. Therefore, he thought, the giant planets should rest on a relatively large-scale solid core. Did they think… because observations made on an exoplanet called Wasp-107b now call this conclusion a question.
In 2019, researchers announced that they had discovered. Today, one of these researchers, Caroline Piulet, (Canada), reveals surprising work related to another topic : Wasp-10p b. La Their hearts would be much weaker than the community thought.
Remember that Wasp-107b is an atypical planet. In 2017, it was discovered around 212Of our earth, in . He is almost as tall , But its mass is very less. What is wasp-10 107b Make a call . and his Is also close to him , Is sixteen times more than our Earth . It nowadays visits only at 5.7. So much that he has trouble catching .
Thanks for the data received(Hawaii), researchers at the University of Montreal were able to measure accurately Wasp-10b B oscillation of its host star due to its gravitational pull. Thus he established his mass on the tenth part of Jupiter.
For the first time in the world outside our solar system, Hubble has been used to detect helium in the atmosphere! Exoplanet WASP-107b is 1 of the lowest density planets. While it is about the same size as Jupiter, it has only 12% the mass of Jupiter: https://t.co/9ngmXQdfeWpic.twitter.com/S8BPXdMHUr

Is not an incredibly very large core
Astronomers then conducted an analysis to determine the internal structure of the planet. Their conclusion: mass ofWasp-10 Was B should not be more than four times that of our Earth. Thus, more than 85% of the planet’s mass will be located in a thick layer. Around this nucleus. this is amazing. Because you should know that , For example – whose mass comes close to Wasp-107b – does not present more than 15% of its mass in this gas layer.
Until now, researchers believed that the formation of a relatively large-scale nucleus was necessary. A state without which the planet could not sustain so many layers of gas. But this discovery about Wasp-107b suggests that Form more easily than thought astronomers. It can be formed especially at some distance from its star – where the gas is cold to facilitate gas. – Before migrating to its current position.
Other questions still remain unanswered about Wasp-107b. The atmosphere of this type of planet, for example, must be rich in methane. However, the observations, Done in 2018, show the opposite. Researchers now plan to reevaluate these results in light of their new findings about the mass distribution of exoplanet. And perhaps find out if the mechanism can explain such destruction of methane.
