Age distribution of stars in boxy/peanut/X-shaped bulges formed without bar buckling

Age distribution of stars in boxy/peanut/X-shaped bulges formed without bar buckling

Some barred galaxies, including the Milky Way, host a boxy/peanut/X-shaped bulge (BPX-shaped bulge). Previous studies suggested that the BPX-shaped bulge can either be developed by bar buckling or by vertical inner Lindblad resonance (vILR) heating without buckling. In this paper, we study the obser...
