The high metallicity ring-like region at 5 kpc from the Galactic Center shows an important excess of λ2.4 μm emissivity, compared to the solar neighborhood. The purpose of this work is to account for this excess by means of an evolutionary model of a synthetic stellar population. We find that this emissivity, principally due to supergiants, is dramatically increased by the interaction of a high present star formation rate (SFR) and a high metallicity Z which together produce a strong increase of the NRSG/NG ratio (red supergiant number over giant number).
A simultaneous fit of these constraints to observations is proposed, and provides information on SFRs, stellar populations and integrated colors B-V, V-K of both regions.
