Case B: Mass Ratio 3:1, NS Spin 0.17, 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 . These figures highlight the emergence of the magnetically-driven jet. 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 we find that an incipient jet is launched after $\sim 3500M\simeq 88(M_{\rm NS}/1.4M_\odot)\,\rm ms$ following merger, which is shorter than the time in the high prograde spin case (Case C).
