Based on current 2.4-micron observations of the Galaxy (see Okuda et al. in this Symposium), we have proposed a specific model for the bulge component. This model is a concentric spheroid with an axial ratio of ∼0.5; ρ(a)∞(a2+ac2)−1exp(-(a/ao)2), where ao = 2.5 kpc and ac = 0.14 kpc respectively. A constant mass-to-luminosity ratio M/Lv≃7.6 is assumed, which yields the relevant rotational velocity in the inner region (Figure 1); the absolute velocity is normalized to 250 km s−1. This value of M/Lv is likely to meet with giant-rich synthetic models for the nuclear bulge of M31.
