The recently discovered exoplanets, Kepler-107b and Kepler-107c, could offer a unique view of world formation.
Astrophysicists studied the Kepler-107 exoplanetary system using the Nazionale Galileo Telescope (TNG), located in La Palma, Spain.
The study suggests that differences in exoplanets in a single compact system are due to the fact that they are formed under very different conditions, or perhaps because of a post-training event has significantly changed their densities.
The exoplanets Kepler-107b and 107c have radii of 1.53 and 1.59 respectively (relative to the radius of the Earth), orbital periods of 3.18 and 4.9 days, but densities of 5 , 3 and 12., 65 grams per cubic centimeter.
What further intrigues scientists is that Kepler-107c is an outer planet and has a density as high as the outer planets of the solar system such as Jupiter, Saturn, Uranus and Neptune have much lower densities because they are formed of cold gases and ice, while the inner planets are made of materials that have survived solar radiation, such as silicate and iron.
The researchers also believe that Kepler-107c may have suffered a catastrophic collision that tore its silicate coat, leaving only the iron core at 70%.
"It is thought that the impacts of giants played a key role in the formation of our current solar system […] The Moon is probably the result of such an impact, and the high density of Mercury is also , and the great Charon satellite of Pluto was probably captured after a gigantic impact, but until now, we had found no evidence of gigantic impacts on planetary systems other than ours, "he said. explained Dr. Zoe Leinhardt, computer scientist and co-author of the study, quoted by Popular Mechanics magazine.
"If our hypothesis is correct, it would bind the general model we have for the formation of our solar system with a planetary system very different from ours."
The mysteries of our solar system, such as doubts regarding the metallic core of Mercury that covers about 85% of its body, could be elucidated with the discovery of the origin of Kepler-107c [19659007] (function (d, s, id)
