Evolution of the surface rotation velocity (top panel), the stellar rotation rate over the critical rotation rate (middle panel), and stellar angular momentum (bottom panel) as a function of system age obtained with TREMOR. The initial stellar rotation rate is Ω_rot/Ω_crit = 0.05, the initial eccentricity was set to 0.1, and the initial orbital period of the system is 1.26 days. The green track corresponds to the evolution predicted with the formalism from Zahn (1975, 1977). The black line corresponds to the rotation frequency for which the system is pseudosynchronised.
