Since the realistic equations of state are softer than the 2 one, each neutron star becomes more compact (cf. Figure 2). This implies that the merger will set in at a more compact state which is re ...

The short radiative cooling time of the gas means that the feedback must be more or less continuous. How the jet power, which is highl ...
