用quark star造句子，“quark star”造句

Pulsars, neutron stars and quark stars are then created based on their mass.

That is , a quark star is a black hole, while the black hole formation has not collapsed to one point yet.

Besides small thermal radii, low-mass quark stars could spin very fast, with a negligible effect of r-mode instability.

Though the maximum masses and corresponding radii are similar, bare strange quark stars and normal neutron stars could be distinguished in the regime of low masses.
