Spatial and temporal variations of log density relative tothe initial, smooth CAK steady state at t = 0, with color ranging from densities a decade below the t = 0 value (blue) to a decade above (red). The vertical variation extends from the subsonic wind base at the stellar surface R* to a height of one R* above. For clarity, the lateral variation is displayed over twice the horizontal box length 0.1R* . The upper row shows time evolution over the initial 100 ks after the CAK initial condition in steps of 10 ks; the bottom row uses the same step size of 10 ks to show the evolution between 300 and 400 ks, long after the initial condition has developed into a statistically steady turbulent flow.
