Temporal behavior of radial velocity and intensity of the 1 M_⊙ model st28gm05n056. Top panel: Spherical averages of radial velocity as a function of radial distance and time. Bottom panel: Normalized intensity (luminosity seen by an observer) corresponding to the view in Fig. 13. The colored vertical lines (red, orange, green) at about t = 138 yr mark the instants selected for that figure. The timer for this model does not start at zero but at about t = 111 yr.
