10 m interferometry of disks around young stars
arXiv:0810.5534 · doi:10.1088/1742-6596/131/1/012023
Abstract
This contribution reviews results from interferometric observations of circumstellar disks around young stars of 3 M, performed with the MIDI instrument operating in the 10 m spectral region. Two main topics, the disk structure on 1-10 AU scales and the dust properties in the same region, are illustrated with several examples of MIDI studies, covering various evolutionary stages. The spatially resolved observations largely confirm SED-only based hypotheses on disk structure, yet also reveal degeneracies that may occur in such SED modeling. The properties of the dust on the disk surface show a strong radial dependence: the dust close to the central star has generally larger grain sizes and in particular a much higher crystallinity than the dust in more remote disk regions.
