Query: Gas and dust in the inner disk of the Herbig Ae star MWC 758   In this Letter we investigate the origin of the near-infrared emission of the
Herbig Ae star MWC 758 on sub-astronomical unit (AU) scales using spectrally
dispersed low resolution (R=35) AMBER/VLTI interferometric observations both in
the H ($1.7 \mu$m) and K ($2.2 \mu$m) bands. We find that the K band
visibilities and closure phases are consistent with the presence of a dusty
disk inner rim located at the dust evaporation distance (0.4 AU) while the bulk
of the H band emission arises within 0.1 AU from the central star. Comparing
the observational results with theoretical model predictions, we suggest that
the H band emission is dominated by an hot gaseous accretion disk.
