Black And White 30th Birthday Party

Metro hot!

astronomers a group called Super Wide Angle Search for Planets (search for planets using super wide angle) found, looking through telescopes in the infrared, a gaseous planet is even hotter than some stars : 3200 ° C, and has about 4.5 times the mass of Jupiter.

I have dubbed WASP-33b, and orbits its star once every 29.5 hours, ie, an orbit extremely close! And if the planet is hot, its parent star is one of the hottest known to harbor planets. That blissful star is burning its fuel before our eyes, burning 7160 ° C, or much more than our sun, whose surface temperature is "only" 5600 ° C.

Experts are my interest in this planet because they want to know if their external atmospheric layers are hotter than the interior or vice versa. One would expect, given the proximity to the sun, the exterior of WASP-33b was hotter than inside, but cases have been opposed.
