Reply to comment by tameriaen in Bizarre star may have a solid surface, according to X-ray observations. Astronomers have now spotted a super strange one that seems to have a solid surface. Its intense magnetic field is strong enough to overcome its blistering temperatures and “freeze” its outer layers into a solid crust. by MistWeaver80

Aren't quark stars black holes?

We don't know what's on the other side of the event horizon -- could be quark star, plank star, singularity, whitehole universe, or something else. Your guess is as good as mine.

That said, it's thought that neutron stars might have quark matter cores, and there's a handful of stars (without event horizons) as candidates for quark stars.

I had only known quark stars as proposals for what's inside a black hole, didn't know they could be neutron star cores.

That's interesting.
