| Abstract: |
Dust is formed in the outer atmospheres and winds of AGB stars and
severely affects their observed spectra and colours.
Synthetic JHK colours from a grid of time-dependent C-star models
are presented and compared to observed colours. The combined effects
of pulsation and dust are significant, especially for the coolest and
most luminous models. We are now extending the calculations with respect
to effective temperature, luminosity, stellar mass, and pulsation
amplitude, as well as the carbon excess. |
