Distribution and studies of the infrared stellar populationinthe Galaxy. V. Other clear regions around the galactic centre.
Abstract
A number of stars with K less than or equal to +9.0 in three clear regions located at latitudes of approximately -3.5, -4.0, and -4.5, respectively, in the general direction of the Galactic center are studied. An exponential disk model is used to separate these regions into disk and bulge cumulative counts functions (CCF). It is found that, for the case of Baade's window (BW) (Ruelas-Mayorga and Teague, 1992), the disk is dominant at bright magnitudes, whereas the bulge dominates at the faint end of the CCF. The slope of the bulge CCF is steeper than that for the disk in all three cases confirming the result obtained for BW. The two color JHK diagram and the K vs J-K diagram for the three regions reveal that the stellar population in these areas is similar to that studied in BW.
