RIA Novosti, citing the Astrophysical Journal Letters, said that astronomers were able to detect in the constellation Pisces unusual celestial body outlaw, a cross between a giant planet and star-brown dwarf, SIMP0136.
Étienne Artigo (Ethienne Artigau) at the University of Montreal (Canada) explains: “the Translation SIMP0136 of the number of brown dwarfs to the elite club of “independent” planets have escaped from their stars, was a pleasant discovery for us. In the past we’ve already found hints of the existence of weather on this object, even when we thought it was a brown dwarf, and its study will help us to shed light on the composition and behavior of the atmosphere on other exoplanets“.
Brown dwarfs are so-called failed stars with a mass less than 7% of the mass of our Sun. They are not large enough for thermonuclear reactions, so gradually extinguished and cooled. On brown dwarfs, there is weather, clouds of lead and minerals — that’s why many astronomers believe that this was not the star and a large planet.
As for SIMP0136, the planet is on the boundary between large planets like Jupiter and brown dwarfs. The mass of an object in the 12-13 times more than the largest planet in the Solar system, the radius 20% greater than that in Jupiter. The surface temperature is about 800 degrees Celsius.
Scientists believe that SIMP0136 appeared next to another star, and then was thrown out of the system, becoming the so-called planet “rogue”.
