The effects of bar–spiral coupling on stellar kinematics in the Galaxy
The effects of bar–spiral coupling on stellar kinematics in the Galaxy
We investigate models of the Milky Way disc taking into account simultaneously the bar and a two-armed quasi-static spiral pattern. Away from major resonance overlaps, the mean stellar radial motions in the plane are essentially a linear superposition of the isolated effects of the bar and spirals. Thus, provided the …
