Panels (a)–(c): mass fallback rate to the BH as a function of time for the disruption of a 1M_⊙ star at three different ages and impact parameters by a 10⁶M_⊙ BH. Panels are grouped by impact parameter β. The result for a γ = 4/3 polytrope from Guillochon & Ramirez-Ruiz (2013), scaled to the radius of the ZAMS Sun, is in dotted black. The Eddington limit for this BH, assuming a radiative efficiency of ϵ = 0.1 and an electron scattering opacity of κ = 0.34 cm² g⁻¹, is shown by the dotted–dashed line. Panel (d): mass fallback rate for full disruptions of a 1M_⊙ star and 3M_⊙ star at ZAMS and TAMS.
