Comparison of the specific angular momentum of the accreted wind matter used in V20 (Eq. (18), Iben+1996) to the analytical value derived by Shapiro & Lightman (1976) (SL1976) for the stellar and binary parameters of WR79, as a function of the time since BH formation. We also show the decrease in the amount of specific angular momentum carried by the wind when the typical wind velocity for O type stars is introduced in Eq. (18), denoted by ‘Iben+1996 updated’.
