We analyze a sample of 753 S0 galaxies from the MPL-10 of Mapping Nearby Galaxies at Apache Point Observatory survey and investigate the gas–star kinematic misalignment and merger remnant fraction in galaxies with different morphological types. The misalignment fraction in S0s is the highest among a...
