It is possible a very heavy neutron star just slammed into one that was not neutronized yet ? Plain old mechaqnical collision at galactic speeds ?
Collisions are possible but highly improbable.Wolf kotenberg wrote:

And there is no such thing as a very heavy neutron star:

<<A typical neutron star has a mass between 1.35 and about 2.0 solar masses. In general, compact stars of less than 1.44 solar masses – the Chandrasekhar limit – are white dwarfs, and above 2 to 3 solar masses (the Tolman–Oppenheimer–Volkoff limit), a quark star might be created; however, this is uncertain. Gravitational collapse will usually occur on any compact star between 10 and 25 solar masses and produce a black hole.>>
