They detect the hottest planet
According to the scientific magazine American New Scientist, the temperature of this new planet is own of a star. In fact there are, them as hot as WASP-12b, that it is as well half of hot that the surface of our Sun.
Its mass is 1.5 times greater than the one of Jupiter, but a day in orbiting its star only takes. The distance between both is quite short, which causes that WASP-12b is so hot.
The detection of this planet was possible thanks to a project in that two telescopes have collaborated, one of them of the Institute of Astrophysics of the Canary Islands. The project, SuperWASP call (by Planet Search by Ample Super Angles, in English), consists of looking for planet signals that journey , that is to say, that pass in front of their stars attenuating their luminosity facing the Earth.
The observations of 'tránsito' allow the astronomers to calculate the size of the planet and the orbital distance and, from there, to value the amount of stellar light that falls envelope they and therefore, their heat.
The previous record of temperature was adjudged to HD149026b, a planet with a completely black surface and that stays to 2040ºC.
But WASP-12b also shows the record of orbital speed. The majority of exoplanetas takes three days or more in completing their orbits, for that reason the rapidity with which this new planet orbit its star has been a surprise for the astronomers.
