ISO-SWS spectra of the C-rich AGB star R Scl and dynamical model atmospheres

Hron, J., Loidl, R., Höfner, S., Jørgensen, U.G., Aringer, B., Kerschbaum, F.

We have monitored the spectral variations of the carbon rich AGB star R Scl in the 2-45 mum range using the ISO-SWS instrument. We have also computed hydrostatic and hydrodynamic model atmospheres and corresponding synthetic spectra representative for two phases of R Scl. There is good qualitative agreement between observations and models in the near IR. This demonstrates the theoretical progress and the potential of analysing carbon star spectra with self-consistent dynamical models.
