Scientific paper

The evolution of the infrared spectra of asymptotic giant branch (AGB) stars has been obtained by time-dependent radiative transfer models. Based on a simple mass-loss formula, the evolution of intermediate mass stars on the AGB has been calculated. The results of these models are compared with the photometric and spectroscopic observations of AGB stars by the IRAS satellite. Due to the availability of a large uniform sample of high-quality data, the formula of mass loss for AGB stars can be critically tested. The present mass-loss formula suggests that AGB stars with the 10-micron silicate feature in absorption are mostly stars with main-sequence masses higher than 3 solar masses.
