Figure 18: Summary of potential outcomes from NS-NS mergers. Here, is the
threshold mass (given the EOS) for collapse of a HMNS to a BH, and is the binary
mass ratio. ‘Small’, ‘massive’, and ‘heavy’ disks imply total disk masses ,
, and , respectively. ‘B-field’ and ‘J-transport’
indicate potential mechanisms for the HMNS to eventually lose its differential rotation support and
collapse: magnetic damping and angular momentum transport outward into the disk. Spheroids are
likely formed only for the APR and other stiff EOS models that can support remnants with relatively
low rotational kinetic energies against collapse. Image reproduced by permission from [282], copyright
