Mass accreted before critical rotation is reached (relative to initial mass) by uniformly rotating CEMP-s star progenitors for different values of the specific angular momentum of accreted material j_a: a) effect of different mass accretion rates in the M_AGB = 1 M_⊙ case); b) effect of different primary masses (age at the onset of mass transfer) in the Ṁ = 10^-8M_⊙ yr^-1 case. The case of j_a = 2 × 10¹⁷ cm² s^-1, Ṁ = 10^-8M_⊙ yr^-1 is not shown because in all models ΔM exceeds 0.35 M_⊙ (dash-dotted line), at which point the computations were stopped.
