Hot Jupiter under the eye of Hubble and Spitzer
HD 209458b is probably one of the best known and most studied exoplanets. It is also known by the name of Osiris. Two times less massive than Jupiter , it rotates at 6.7 million kilometers of HD 209458, a star very similar to our Sun 150 light years from Earth, in just 3.5 days. HD 209458b was spotted by the radial velocity method . But soon, astronomers have found that its orbit led him to cross the line of sight joining us its star. There are already seven years, a team of astronomers had analyzed Hubble with the light passing through the atmosphere of HD 209458b exoplanet during a transit in front of its star host . The presence of water molecule was then established.
Wasp 12b orbit in just a day or so around Wasp 12, a sun-like star located about 870 light years away in the constellation Auriga. http://enjoycoloring.com/tag/sports/ Discovered using SuperWASP (acronym for Super Wide Angle Search for Planets ), the gas giant has a mass about 1.4 times that of Jupiter. She is dying, so hot it evaporates. Observations of Spitzer in infrared already showed the presence of a little water vapor, large quantities of carbon monoxide carbon (CO) and especially methane (CH 4 ). Hubble confirmed the presence of water in 2013.
