Detection of atmospheric haze on an extrasolar planet: the 0.55-1.05 µm transmission spectrum of HD 189733b with the HubbleSpaceTelescope.

Abstract (from CDS):
We observed an almost featureless transmission spectrum between 550 and 1050 nm, with no indication of the expected sodium or potassium atomic absorption features. Comparison of our results with the transit radius observed in the near and mid-infrared (2-8 µm), and the slope of the spectrum, suggest the presence of a haze of submicrometre particles in the upper atmosphere of the planet.
