Post-disruption fractional mass loss, Δm_⋄/m_⋆, for a star of mass 1 M_⊙ (left) and 0.5 M_⊙ (right), due to a BH of mass 10 M_⊙ (top) and 40 M_⊙ (bottom), as a function of impact parameter b and MS age (H_c abundance). The dashed line at the top signifies the full disruption of the star. The fractional mass losses are largely independent of BH mass. Mass loss is higher for lower b values, and this decreases roughly exponentially (best-fit lines and standard error regions shown) with increasing b. A less evolved star (higher H_c) loses more mass for the same value of b. A 0.5 M_⊙ star has a higher mass loss than a 1 M_⊙ star for the same b.
