Absolute value of the mass loss rate (full line) and mass accretion rate (dashed line) as a function of the donor’s mass for the best models. Horizontal black lines represent the estimations for the mass loss rate derived from the works of C+12, O+11 and the estimation we obtained with Webbink et al. (1983). The donor’s mass (M_d = 0.3 M_⊙) is indicated by a vertical black line, with a shaded area representing the observational error. The dots depict the donor’s mass and mass loss rate (or mass accretion rate) at t_obs for each model.
