Description
The apparent galactic rotation curve as inferred from H I and CO terminal velocities shows a narrow peak at r approx. = 500 pc, and a steep decline for 600 pc <=r<=1.5 kpc down to a rather broad minimum around 2.8 kpc. In this paper it is shown that this morphology can be reconciled with the bulge density distribution determined by infrared observations and the local density of spheroid stars only if the bulge of our Galaxy is non-axisymmetric and the resulting potential triaxial.
