Double-peaked emission lines in M17-B243. These profiles indicate the presence of a circumstellar rotating disk. The X-shooter spectrum is shown with the solid black lines and the two Gaussian functions fitted to the profiles are shown in red. The lines are plotted in the heliocentric frame and the dashed grey line represents the radial velocity of the star. Each line is labelled on the left side of the plots and the peak-to-peak separation is shown on the right side of the profiles.
