摘要：Using data from the FIS AKARI All-Sky Survey, we make a first step towards the estimation of the contribution from Asymptotic Giant Branch (AGB) stars to the far-infrared (FIR) flux from the Milky Way.We estimate the contribution from the AGB, and post-AGB, stars to the total flux generated by point sources outside the Galactic plane.Additionally, we present the positions of different types of AGB, and post-AGB, stars in the FIR color-color diagrams.Our main conclusion is that there is a high contribution from AGB stars, and particularly post-AGB stars, to the FIR flux coming from point sources in the outer parts of the Milky Way and possibly other Milky Way-type galaxies.FIR colors of different types of AGB stars remain similar but post-AGB stars are redder in the FIR and, as a result, contribute more to the total Galaxy flux density at longer FIR wavelengths. Key words Dust AGB stars post-AGB stars far-infrared all-sky surveys.
