Now, according to new data from NASA’s Chandra X-ray Observatory and the European Southern Observatory’s Very Large Telescope, astronomers can tell that the planet is being hit with x-rays about a hundred thousand times more intense that what Earth receives from the sun.
“This planet is being absolutely fried by its star,” study co-author Sebastian Schröter, of the University of Hamburg in Germany, said in a press statement.
The star is already all growed up, with an estimated age between 100 million and 300 million years old.
But CoRoT-2a is also very active for its age—the star is producing all those x-rays thanks to a strong and turbulent magnetic field, which is a feature of much younger stellar bodies.
The study authors surmise that the star’s activity may be an effect of the planet orbiting relatively close, at a distance about ten times the span between Earth and the moon.
“Because this planet is so close to the star, it may be speeding up the star’s rotation, and that could be keeping its magnetic fields active,” study co-author Stefan Czesla, also from the University of Hamburg, said in the statement.
