Figure 20

Figure 20: Left: Summary of the remnant disk mass as a function of the BH spin for a fixed EOS (Γ = 2 EOS), NS compactness (𝒞 ≈ 0.145), and mass ratio (Q = 3), computed by the UIUC, CCCW, and KT groups. The vertical axis shows the fraction of the disk mass Mr>rAH ∕MB where MB is the baryon rest mass of the NS. “CCCWin” shows the results by the CCCW group with inclination angle of the BH spin, 40, 60, and 80 degrees (from upper to lower points). Right: The same as the left panel but for the disk mass in the solar mass unit for more compact NS (𝒞 ≈ 0.172) with a piecewise polytropic EOS (HB). The simulation was performed by the KT group [109]. For both panels, the disk mass is measured at t ≈ 10 ms after the onset of the merger (for the Γ-law EOS, MNS is assumed to be 1.4M ⊙).
