Fig. 14


CO2 flux versus stellar luminosity for three different features in the spectrum. All fluxes have been normalized to the flux of the 1 L model. Both the flux in the 14.7 to 15 μm region, which corresponds to the v2Q-branch, and the flux from the 0110Q(6) line have a nearly linear dependence on the stellar luminosity. The dependence of the 0001R(7) line at 4.3 μm on source luminosity is more complex.
