| Abstract: |
Based on dynamic model atmospheres for Mira variables with
carbon-rich atmospheric chemistry we have calculated synthetic
spectra and photometry for standard broadband filters from the visual
to the near-infrared. The modeling allows us to study in detail the
influence of two effects characteristic of such objects: (i)
the pulsation of the stellar interior, and (ii) the dusty
circumstellar envelope resulting from an outflow containing grains
of amorphous carbon. A comparison with observational data shows that
the models used describe the outer layers of pulsating, mass-losing
AGB stars reasonably well. |
