An exoplanet with an infernal atmosphere: 1000 kph winds; 3000 degree temps

10 abril 2015

Astronomers have come to measure the temperature of the atmosphere of an exoplanet with unequaled precision, by crossing two approaches. The first approach is based on the HARPS spectrometer and the second consists of a new way of interpreting sodium lines. From these two additional analyses, researchers have been able to conclude that the HD189733b exoplanet is showing infernal atmospheric conditions: wind speeds of more than 1000 kilometers per hour, and the temperature being 3000 degrees. These results open up perspectives to approach the study of exoplanet atmospheres.
