Fig. 10


Lyman-α line profile. Four spectra, corresponding to the four HST orbits of the September 2011 observations, are displayed as a function of radial velocity relative to the star. The black and blue lines show the fluxes before the planet transit; the green line with error bars at the 1σ level shows the flux during the transit; the red line shows the flux after the transit.
