For the first time astronomers have declined the three-dimensional structure of the atmosphere of a planet beyond our solar system, revealing three layers like a wedding cake on a cruel hot gas planet which is bigger and hot stars than our sun Remains close to
Researchers also called a planet as a tileos, through the atmosphere of the wasp -121B, which is a stratification of layers with various chemical compositions and acute winds, combining all four telescopes of Chile -based very large binoculars of the European Southern Observatory I understood
So far, researchers are able to determine atmospheric chemical composition for some planets outside our solar system – called exoplanet – but how the vertical structure or chemical elements were distributed.
WASP-121B is a “Ultra-Hot Jupiter”, a class of large gas planets that is located close to its host star, which they are extremely hot. Its environment is mainly composed of hydrogen and helium, such as Jupiter, the largest planet of our solar system. But the wasp -121B environment has never been seen before.
Researchers distinguished three layers in search of the presence of specific elements. The lower layer of the wasp -121B was characterized by the presence of iron – a metal in gaseous form due to incredible heat of the atmosphere. The winds move the gas from the eternal warm side of the planet to their cooler side.
The middle layer was characterized by the presence of sodium, in which a jet stream was blowing circularly around the planet about 43,500 miles (70,000 km) per hour – stronger than any wind in our solar system. The upper layer was painted based on its hydrogen, some layer of which was lost in space.
“This structure has never been seen before and the current predictions suggest how the atmosphere should behave,” said the Lagrange Laboratory at the European Southern Observatory Julia Victoria Sedel and the Lagrange Laboratory at Observatore de La Kota D’zur in France, and France, Lagrange Laboratory, Prominent French writer. Studies published in Journal Nature this week.
Researchers also detected titanium in gaseous form in the atmosphere of wasp -121B. On Earth, neither iron nor titanium are present in the atmosphere because they are solid metals due to the lower temperature of our planet, relative to the wasp -121B. The Earth has a sodium layer in the upper atmosphere.
“For me, the most exciting part of this study is that it operates on the boundary of what is possible with current telescopes and equipment,” said Bibiana Prinoth, co-writer of the study, said, in astronomy at Lund University in Sweden A doctoral student.
The WASP-121B has almost the same mass similar to Jupiter, but doubles the diameter, causing it to puffer. This constellation is located about 900 light from the earth in the direction of Pulis. A light-year is a distance lighting in a year, 5.9 trillion miles (9.5 trillion km).
The WASP-121B has been locked the grasshopper, meaning that one side of it faces always stars and the other side is far away, as if the moon is on Earth. The temperature of the front side of the star is about 4,900 degrees Fahrenheit (2,700 ° C/3,000 ° C). The other side is about 2,200 degrees Fahrenheit (1,250 ° C/1,500 ° C).
The planet revolves around its star about 2.5% of the Sun’s Earth’s distance. It is about one third of its star compared to the inner planetary mercury of our solar system, which is for the Sun – so close that it completes a class in 1.3 days.
Its host star, called the WASP-121, is about 1–1/2 times the mass and diameter of the sun, and warm.
Astronomers discovered small rocky planets, which are capable of harassing life, being able to exclude the structure of an atmosphere of an exoplanet.
“In the future, we will probably be able to provide equal observation for small and cold planets and thus more similar to the Earth,” Printh said, especially the completion of the European Southern Observatory in Chile with a very large binoculars of the European Southern Observatory The reason is due to the completion of Chile in Chile till the end of Chile. Decade as the world’s largest optical telescope.
“These detailed studies are necessary to provide references for our place in the universe,” Sedel said. “Is the Earth’s climate unique? Can we get from one of our data points – Earth – actually explain the entire population of exoplanets?”
“With our study we have shown that climate can behave differently that is predicted. There is much more diversity than what is in our house,” Sedel said.
