Notes. The parameter j_impact (j_disc) is the specific angular momentum computed with ballistic motion equations (boundary-layer treatment), and all Ṁ are defined positive. The superscripts “Wind” (“RLOF”) refer to stellar wind (Roche lobe over-flow) contributions, while the subscripts “acc” (“loss”) denote mass accretion (loss). Torques with the superscript “B” denote torques due to the presence of a magnetic field (see text for details). Also, I is the star’s momentum of inertia; f_jacc is a free parameter controlling the specific angular momentum accreted by wind accretion (Bondi & Hoyle 1944); and f_Σ is another free parameter (set to 1 for the simulations presented in this paper) setting the specific angular momentum carried by the matter leaving the system in units of the specific angular momentum of the binary system j_orb.
