Angular velocity of rotation in the star’s interior Ω(m) during the common envelope stage and after its completion. The angular velocity distribution is shown for ζ = 0.8 (top line), ζ = 0.5 (middle line), and ζ = 0.2 (bottom line) for the following time instants during the common envelope stage (left panel): 1 year (solid line), 10 years (dashed line), 30 years (dash-dotted line), and 100 years (thick solid line). The time instants after its completion (right panel) are 10³ years (thick solid line), 5 × 10³ years (solid line), 10⁴ years (dashed line), and 5 × 10⁴ years (dash-dotted line).
