Figure 1: AMBER calibrated spectrum of 51 Oph around the 2-0 and 3-1 bands of the CO overtone at 2.3 microns. For comparison purposes is plotted (dashed line) the same spectrum measured with the TNG spectrograph (L. Testi, private communication). Note that we did not plot the TNG spectrum between the two bandheads because of irrelevant instrumental artifact. |

Figure 3: LR-K calibrated visibilities as a function of the projected baselines, for the three observations, and overplotted best model (lines). In each panel, colors red, blue,and green correspond to baselines G1-D0, D0-H0, and G1-D0 respectively. |

Figure 4:
Spectral energy distribution of 51 Oph taken from
literature (Waters et al. 1988) (crosses) and superimposed best fit
model (solid line) using MCFOST dusty disk model. The main parameters that are fitted are the
inner radius

Figure 5:
MR-K continuum visibilities (top panel) and LR-K
visibilities as a function of the baseline and and overplotted
MCFOST model arising from SED fitting (lines). The color code is the
same than in Figs. 2 and
3. We can see that this model, with inner
radius equal to the dust sublimation radius, is incompatible
with the interferometric data, with a resulting ![]() ![]() |
