World boils like a star

The KELT-9 star is almost twice as hot as the Sun, which has a tremendous effect on its closest exoplanet - the KELT-9 b gas giant. The world is heated to such extents that temperatures on the day side reach some 4,316°C – only 1,200 degrees lower than the Sun's surface. The intense ultraviolet radiation that the star mercilessly uses to “sandblast" the planet is so intense that it burns the planet's atmosphere, according to scientists. A conservative estimate says that at worst, the star could eliminate the planet's atmosphere completely over a very short period of time.
