If a neutron star accumulate materials from its companion star ,then it's mass exceeded Tolman–Oppenheimer–Volkoff limit, it will collapse into a blackhole! My question is ,in this case ,it will produce "gamma-ray burst"?

HI Magnetar,

I beleive no one can answer the question you ask. All we know is that we measure gamma ray bursts, but until now, no satisfactory explanation of their origin has been found.

Cheers,

In the case of ordinary accretion, neutron stars tend to expell most accreted matter. Due to their intense magnetic fields, this occurs mainly at the poles. When the poles of neutron stars lay close enough to our line of sight, it produces a pulsar. Pulsars invariable appear to 'spin down', signifying a slowing of rotation. If a neuton star were rapidly gaining mass, it should tend to rotate faster. In the case of inspiralling binary neutron stars, mergers are thought to account for short gamma ray bursts, consistent with your idea. Formation of a black hole is probably inevitable in these cases. About 5% of neutron stars are observed to have a neutron star companion.

Is it possible for a Neutron Star to explode?

Could a scenario exist that would allow a Neutron Star to become unstable and explode with enough force to send chunks and particles away at above the overall escape velocity of the combined mass of the star? If so, could the chunks and particles of the explosion that did so, be stable enough to travel large distances and cause havoc in another star system? And if that is so, what would be the effect of a chunk of a neutron star lets say 200 ft in diameter do when it enters our solar system?

Neutron star material cannot be expelled as a condensed matter entity. Were a chunk to attempt to leave the gravity well, it would decompress [explode].
