Fraction of mass accreted by the companion as a function of v_∞/v_orb. The dotted line corresponds to BHL accretion rate with _BHL = 1, and the dashed line to the accretion rate for a geometrical cross section of size R_sink. Dots correspond to models in which the orbital separation is 5 AU and stars to models in which a = 3 AU. The values shown are measured at a radius of 0.4 R_L,2 (β_0.4RL,2).
