Orbital Support and Evolution of Flat Profiles of Bars (Shoulders)

Many barred galaxies exhibit upturns (shoulders) in their bar-major-axis density profile. Simulation studies have suggested that shoulders are supported by looped x _1 orbits, occur in growing bars, and can appear after bar buckling. We investigate the orbital support and evolution of shoulders via...
