If the magnetic stress bears up the gravitation in the stellar evolution, the big mass neutron star over the neutron - star mass can not collapse into a black hole.

如果在恒星演化过程有磁应力来支撑引力，超过中子星质量上限的大质量中子星则不致于坍缩成黑洞。

Each proton (or neutron) has about two thousand times the mass of an electron.

每一个中子或者质子的质量都是一个电子的两千倍。

All the mass measurements that have been done to date of these neutron stars where you see the pulsations... all of them are very close to 1.4 solar mass.

对于这些中子星的，质量测量，你看到脉冲，所有的都很接近于。，1。4倍的太阳质量，对此有个很好的解释。

Depending on its initial mass, it might collapse to a compact hot star known as a white dwarf (when the star's mass is less than 1.4 times the mass of our sun) or to a neutron star (for stars 1.4 to about three times the mass of our sun) or to a black hole (for stars more massive than three times the mass of our sun).
