Lenticular (S0 and SB0) Galaxies S0 and SB0 galaxies are transition objects. They are disk systems, but otherwise are like ellipticals (Pop II, no star formation, no spiral arms, and little cold gas or dust). Sa and SBa Galaxies Sa and SBa galaxies have a large (dominant) Pop II bulge, and a very smooth disk with only a trace of spiral arms.
