摘要：

We present new 8-13-mu-m speckle interferometry of seven oxygen-rich stars with circumstellar dust shells. Six of the shells are partially resolved with only the shell around alpha-Ori being fully resolved. We develop a simple shell model and derive the wavelength dependence of the optical depth for the dust around alpha-Ori. The similarity of this dependence, to other determinations is discussed.
