Stellar sources in the ISOGAL outer bulge fields (7 and 15 mum ISOCAM observations)

Résumé

We report the study of ISOGAL fields in the outer galactic bulge. We have combined 7 and 15 mum ISOCAM observations with DENIS IJK_s near-infrared data to determine the nature of the sources and the interstellar extinction. Most of the ISOGAL sources show evolution of mass-loss rates in the range 10^{-8} to 10^{-6} Modot/year. Most of the detected sources are red giants above the RGB tip; a few of them show an excess in J-K_s and K_s-[15] colors. These sources are detected as AGB stars with large mass-loss rates.
