Evolution of the kinematic profiles of the 1.5M-A-R4-10 simulation from time t=0 Gyr (orange lines) to t=12 Gyr (blue lines). The intermediate time snapshots are color coded in gray scale. The panels report the rotation profile V_ϕ(r), the V_ϕ/σ(r) profile indicating the ratio between ordered and random motion, the z-component of the angular momentum per unit mass l_z(r), and the anisotropy profile β(r). The time resolution between the plotted lines is ≈64 Myr.
