Bar formation in the isolated model. a) Bar amplitudes A2/A0 and URθ,2, and the bar strength B(t) demonstrate lags, jumps, and exponential growths with a rate ωI ≈ 3 Gyr-1 (the slope is shown by the black dashed curve). b) The pattern speed of the bar Ωp determined as an average centred finite difference of the bar phase (dots), and the spline smoothed Ωp (red curve).
