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.
