Evolution of the surface rotation velocity (top panel), the stellar rotation rate over the critatical rotation rate (middle panel), and stellar angular momentum (bottom panel) as a function of system age obtained with TREMOR. Two initial stellar rotation rates were considered: Ω_rot/Ω_crit = 0.2 and 0.3. The initial eccentricity was set to 0.55, and the initial orbital period of the system is 12.57 days. The black track corresponds to the evolution predicted by single stars models.
