Fig. 5

From left to right: face-on maps of the angular momentum variation ΔL, of the rotational support Lnorm = L/Lcirc, and of the vertical velocity dispersion σz for stars with different birth radii (from top to bottom: rini ≤ 0.4rbar; 0.4rbar ≤ rini ≤ 0.7rbar; 0.7rbar ≤ rini ≤ rbar; rbar ≤ rini ≤ 1.3rbar; 1.3rbar ≤ rini ≤ 1.6rbar; 1.6rbar ≤ rini ≤ 1.9rbar). In this, and in all the following maps, all the quantities have been calculated over pixels whose size is 100 pc × 100 pc. The strong AM redistribution following bar formation is evident from the ΔL maps. The rotational support Lnorm shown in the middle column is the ratio between the average L at a given pixel, and the AM, Lcirc, that a star in circular orbit at the same location would have. In each panel, the stellar bar is aligned with the y-axis and the average initial radius is indicated by a white circle. All the plots correspond to the time t = 2.75 Gyr, as indicated. Angular momenta, and their variation, are in units of 100 km s-1 kpc-1; velocities in units of 100 km s-1.
