Astronomers involved in the project Super Wide Angle Search for Planets (SuperWASP) have discovered the hottest planet called WASP-33b. The planet's temperature is hotter than the temperature of a star.
The planet's existence has been suspected since 2006 but has only confirmed in 2010 yesterday. Known, the planet belong to the type of gas planets with masses less than 4,5 times the mass of Jupiter.
Based on observations with the William Herschel Telescope, WASP-33b temperatures reaching 3200 degrees Celsius. The temperature is hotter than a red dwarf star with a temperature 700 degrees Celsius and WASP-12b is 2.300 degrees Celsius temperature.
One cause of the heat of the planet's temperature is the temperature of the parent star is too hot. Astronomers said the planet's parent star's temperature is 7.160 degrees Celsius, higher than the temperature of the sun is only 5.600 degrees Celsius.
Meanwhile, the other reason is the proximity of WASP-33b orbits the parent star. With a distance of only 7% of the distance between Mercury and the Sun, the planet seemed to be "contaminated" hot parent star.
The study of the planet led by Alexis Smith of Keele University in Stafordshire, England. Through this study, astronomers also know that time is very short revolution of the planet, only 29,5 hours.
Demming Drake of NASA Goddard Space Flight Center in Greenbelt, Maryland who was not involved in the study says, "WASP-33b could help astronomers study the planet characteristics heat is still a mystery."
Things that can be learned as a orbit planet close to its star that has a layer of the atmosphere outside is cooler than the inside layer. This is surprising because the planet is "heated" from the outside.
Deming said, the fact it could be related to the presence of carbon-based compounds that alter how the atmosphere responds to radiation. Certain chemical compounds can be formed by ultraviolet light from the star.
"It certainly would be a planet that you want to see. This is a very rare opportunity to be able to study the planets orbiting the stars that super hot," said Deming in his interview with New Scientist.
