Evolution of the spin parameter a and BH mass M_BH for different simulations. Top: evolution of the spin parameter a for the sEdd_0 (solid blue), sEdd_y (solid orange), sEdd_-z (solid green), sEdd_+z (solid red), sEdd_0.05_0 (dotted blue), sEdd_0.05_y (dotted orange) and sEdd_0.05_-z (dotted green) simulations, from the moment super-Eddington was allowed (t = 206.4 Myr). Bottom: evolution of the BH mass M_BH for the same simulations. For comparison is added the Eddington limit Ṁ_Edd (dashed red). Different initial spin magnitudes and directions play a key role in the BH mass evolution, with slower BHs growing more. When the MADness factor f_MAD is low (sEdd_0.05_0, sEdd_0.05_y and sEdd_0.05_-z), the growth in spin and mass are very similar amongst the simulations.
