Here we explore whether major mergers can provide an alternative way to transform spirals into S0s by analysing the spiral-spiral major mergers from the GalMer database that lead to realistic, relaxed S0-like galaxies. We find that the change in stellar angular momentum and concentration can explain the differences in the λ_Re-R_90/R_50 plane found by the CALIFA team. Major mergers thus offer a feasible explanation for the transformation of spirals into S0s. 0004-6361 10.1051/0004-6361/201526354 https://hdl.handle.net/20.500.14352/24170 http://dx.doi.org/10.1051/0004-6361/201526354 http://www.aanda.org/ Formation of S0 galaxies through mergers Explaining angular momentum and concentration change from spirals to S0s
