Abstract (from CDS):

The stellar populations in the central region of the Galaxy are poorly known because of the high visual extinction and very great source density in this direction. To use recent infrared surveys for studying the dusty stellar objects in this region. We analyse the content of a ∼20x20-arcmin2 field centred at (l,b)=(-0.27°,-0.06°) observed at 7 and 15µm as part of the ISOGAL survey. These ISO observations are more than an order of magnitude better in sensitivity and spatial resolution than the IRAS observations. The sources are cross-associated with other catalogues to identify various types of objects. We then derive criteria to distinguish young objects from post-main sequence stars. We find that a sample of about 50 young stellar objects and ultra-compact HII regions emerges, out of a population of evolved AGB stars. We demonstrate that the sources colours and spatial extents, as they appear in the ISOGAL catalogue, possibly complemented with MSX photometry at 21µm, can be used to determine whether the ISOGAL sources brighter than 300mJy at 15µm (or [15]≤4.5mag) are young objects or late-type evolved stars.
