Descripción
We describe the boxy bulge, long stellar bar and elliptical ring of the
Galaxy. This model has largely evolved from NIR survey work by many
teams and differs from other models with a monolithic ellipsoidal bulge.
We maintain that the structure of the inner Galaxy can only be properly
studied by adequately sampling the entire Galactic plane for |l| <
30°, |b| < 1.5°, and that the bulge is best studied at least
3° from the plane. We briefly report a slight radially outwardly
increasing metallicity gradient along the bar and reaffirm de
Vaucouleurs & Pence's (1978) suggestion that the Galaxy is probably
of morphological type SAB(rs)bc II.
