What Are Bosons?

[Alex K]

Do neutrons become bosons if you add more mass to the neutron star until it exceeds the Landau Oppenheimer volkoff limit?

*googles LOV Limit*

Oh, the LOV is the Chandrasekhar limit for Neutron stars instead of white dwarfs. Ok, no. Iirc, the effect leading to the collapse is this: for nonrelativistic neutrons, the Energy goes with the momentum squared
E~p^2

Close to the speed of light, this becomes E~p according to special relativity.

This changed relation leads to a different relation between Energy and volume: the volume inversely determines the momentum of the Neutrons^3 (think Heisenberg uncertainty for decreasing deltaX), and in the relativistic case the Energy increases more slowly with momentum, therefore increases more slowly as the volume decreases. Thus, the pressure is lower, suddenly not being able to compensate the gravitational pressure any more. Bam, black hole collapse.
