Case D: Mass Ratio 5:1, NS Spin 0.33, magnetized

Density Evolution

These figures show rest-mass density $\rho_{0}$ normalized to its initial NS maximum value $\rho_0=8.92\times 10^{14}\,(1.4M_\odot/M_{\rm NS})^2\rm{g/cm}^{3}$ (log scale) at selected times for this case . White lines denote the magnetic field, arrows denote the fluid velocity, while the BH apparent horizon is shown as a black sphere. Here $M=2.5\times 10^{-2}(M_{\rm NS}/1.4M_\odot){\rm ms}=7.58(M_{\rm NS}/1.4M_\odot)\,\rm km$.

In this case the remnant disc is small ($\lesssim 1.4\%$ of the total NS rest mass), and we do not observe either an appreciable outflow or magnetic field collimation.
