Fig. 4


Squared visibility amplitudes of VY CMa as a function of spatial frequency obtained at the near-continuum bandpass at 2.20–2.25 μm. Also shown are fits of a UD (red) and a PHOENIX atmosphere model (blue). These contribute 50% to the total flux, and the remaining part is attributed to an over-resolved dust component.
