Table 7

Radii (in kpc) of the most important resonances for the Galactic bar and spiral arms MW models – corotation RCR, inner Lindblad resonances RILR, and outer Lindblad resonances ROLR.

Resonance MW1 MW2
bar spiral arms bar spiral arms
RCR 3.6 12.3 5.1 8.1
RILR 1.4 2.8 1.7 2.2
ROLR 6.9 20.4 9.4 13.9

Notes. Values for both non-axisymmetric components and both MW models are given. See Tables 2 and 6 for angular velocities and other model characteristics. The axisymmetric model described in Sect. 2.1 is used for the unperturbed potential.
