Fractional anisotropy (FA) of the accreting material for a star in the simulation. Each dot represents FA for accrual of a mass bin of 0.05 M_⊙. Blue colors mean that the star was part of a multiple system while accreting the corresponding mass, red dots mean that it accreted its material as a single star. The red horizontal lines represent the average of FA over five mass bins, i.e., over 0.25 M_⊙.
