Modeling of Dust around RR Tel

We present a model of inner dust regions around the cool Mira component of the symbiotic nova RR Tel based on observations in the near IR from 1975 to 2002. The JHKL magnitudes taken at the South African Astronomical Observatory and corrected for Mira pulsations were modeled by DUSTY code. The code solves radiative transfer by assuming spherical temperature distribution in the innermost regions around Mira. Dust temperature, grain size, density distribution and optical depth during intervals with and without obscuration have been obtained.
