Was observed for the first time a super-storm in a Exoplanet atmosphere, identified with the logo “HD209458b” and called by astronomers over a “hot Jupiter.”

High accuracy in detecting carbon monoxide in the atmosphere Exoplanet show how the gas moves at high speed in the torrid zone, illuminated by its star that in the cold of the night. Observations and obtain a permit other “firsts” Exoplanet orbital velocity measurement, which makes possible direct determination of the mass.

Results of the study, to be published in the journal Nature, belong to a group of astronomers from Leiden University and the Institutes SRON and MIT, and was made possible thanks to the powerful giant telescope and spectrograph of ESO CRIRES. “CRIRES is the world’s only instrument that can analyze the spectrum with such precision that determines the position of lines of carbon monoxide at a resolution of 1-100000,” said Remco by Kok, one of the researchers involved in the study. “It allows us to measure accurately the first time carbon monoxide gas velocity using the Doppler effect,” he also said.

According to Ignasi Snellen, who led a team of astronomers, HD209458b is a place for those with weak hearts. “After thorough study of the atmosphere composed of carbon monoxide poisoned the planet have found evidence of this a super-wind, blowing at a speed between 5,000 and 10,000 kilometers per hour. HD209458b is an Exoplanet with a mass equal to 60% of that of Jupiter and orbits its star that lies 150 light years from Earth in the direction of the constellation Pegasus.
