Researchers at the Brazilian Federal University of Rio Grande do Norte have discovered a giant gas planet 13 times larger than Jupiter. Naked-Science writes about it.
The planet is in a very old binary system where one of the stars has already "died" and turned into a dark dwarf.
To discover a celestial body, astronomers tracked orbital changes of a star pair KIC 10544976 in the constellation Cygnus. For this purpose, they used data from ground-based observatories and the Kepler Space Telescope.
As a result, we found that the system contains two old stars – red and white dwarfs – that rotate around a common center of gravity. The exoplanet giant is also in the same system that may have already appeared in the last stages of the system's development.
"Maybe it came from a substance ejected from one of the stars when it turned into a white dwarf," one of the authors said.
Earlier it was reported that a planet with a planet-scale storm, Iron and silicate clouds was found.
