摘要：

We present mid-infrared interferometric observations of the Herbig Ae star R CrA obtained with MIDI at the VLTI using several projected baselines in the UT2-UT3 configuration. The observations show resolved circurnstellar emission in the wavelength range 8-13 mu m on a similar to 6 AU scale with a non-symmetric intensity distribution, providing support for an inclined disk geometry. Visibilities are best fitted using a uniform ring model with outer radius in the range 6-10 AU, in the wavelength range 8-13 micron. The inclination of the ring with respect to the plane of the sky is found to be similar to 45 degrees, consistent with the 40 degrees suggested from near-infrared imaging polarimetry (Clark et al. 2000, MNRAS, 319, 337).
