Figure 1

Evolution of the rest mass of the material located outside the apparent horizon, $M_{r>r_{\mathrm{AH}}}$, with an appropriate time shift; in these plots, the time at the onset of the merger is taken as the time origin. The top-left panel shows the results for models with $Q=2$ and $M_{\mathrm{NS}}=1.35M_{\odot }$ for all the EOSs employed in this paper. The top-right panel shows the results for selected models with $M_{\mathrm{NS}}=1.35M_{\odot }$ but with different values of $Q$. The bottom-left panel shows the results for selected models with $Q=2$ but with the different NS mass $M_{\mathrm{NS}}$. The bottom-right panel is the same as the bottom-left panel except for the normalization of the mass, with respect to the initial rest mass $M_{*}$.Reuse & Permissions

Figure 3

Relation between disk mass $M_{r>r_{\mathrm{AH}}}$ and the maximum density, ${\rho }_{\max }$, estimated at $t-t_{\mathrm{merger}}\approx 10\mathrm{ms}$. The maximum density oscillates with time even in the quasistationary phase, and we here plot a value averaged in one oscillation period.Reuse & Permissions
