What Is A Quark Star?

And how close are the current theories in finding these objects.

There is highly unlikely to be such an object ... when the pressure (due to gravitational attraction) is sufficient to overcome neutron degeneracy pressure contraction of the radius of the body will continue until the body is contained within the "black hole" event horizon. And I don't think you could get enough temperature in a non-degenerate core to cause significant quantities of free quarks before pair production instability resulted in disruption of the core.

If I remember right a quark star is a neutron star that collapses forming a quark star, but these are hypertheotical stars and may not exist.

But saying that I think there are perhaps three stars that could be quake stars but alot more research needs to be done to prove or disprove.

Wikipedia's quark star entry has a section with potential candidates; overdense neutron stars.

By the way, am i the only one who find neutron stars (in all their variety) much more fascinating than black holes?

[Asur84]

I too am a fan of neutron stars Lerxst, however, I would like to see some of the research on these quark stars.

Does the star need to be of a very specific mass to become a quark star? A bit more and it collapse into a black hole, a bit less and it remains a neutron star.

Here is a good article about the possibility of Quark stars.

Yes but surely ElectroWeak Stars are more dense than Quark Stars as elecrtoweak burning of quarks to leptons gives rise to higher degeneracy pressure
