Very Strange Star

Physicists have demonstrated the existence of six types of quarks, but in terrestrial matter found only the two lightest quarks exist. These are the Up and Down quarks that make up the proton ( uud ) and the neutron ( udd ) . Particles that contain heavier quarks , as strange quark ( quark S ) can be produced by accelerators .

Measurements made by Chandra on the star RX J1856.5-3754 and 3C58 pulsar located in the remains of a supernova that exploded in 1181 suggest that this is the first strange stars ever observed.

Now a neutron star is the result of the collapse of a supernova of type II or Ib The precise nature of the superdense matter existing in the core of a neutron star is not yet well known. Some researchers call this neutronium substance which could contain a mixture of superfluid neutrons , electrons and protons . Other particles, such as pions or kaons , may also be present, but now , this has been neither confirmed nor contradicted by observations .

When a massive neutron star is subjected to sufficient pressure caused by the gravity of the star, neutron collapse, releasing the quarks that compose it, thus forming the strange matter . The star becomes a strange star . The strange matter is composed of quarks up, down and strange interconnected directly , similar to the connections between neutrons in the neutronium , this strange star then becomes a kind of unique and gigantic nucleon. A strange star is located halfway between the neutron star and black hole, both in terms of the mass in terms of density, and if enough material is added to a strange star , it will collapse on itself to become a BH. A neutron star diameter is approximately 20 km but a strange star’s about 11 km . The diameter of the star RX J1856.5 - 3754 was estimated at 11.2 kilometers , making it the first strange star ever discovered.

To add some doom porn to this thread I would also like to say that a fun aspect of strange matter is that it is a very effective way to destroy the Earth. Indeed , If we succeed in producing a stable strange quark in a particle accelerator, there would be simply to wait , and gradually the whole earth material would collapse on the strange quark to end up in a little ball of strange matter , an inch in diameter ... Funny, is it not?
Pardon my French.

Hmmm... Destroy the Earth huh ? The risk of that happening, is probably just as big, as the risk of mini black holes getting created, when the LHC started working.

I assume that we will never be able to see a quark with our own eyes, just like black holes will always escape our view.
It is an interesting topic though. Thank you !

Thank you! But micro black holes are not a good solution to the annihilation of the planet. They evaporate way too fast to cause any damage :p

I suppose the real question becomes one of if, ever a Quark S is created in the LHC for example...just how gradual would this hypothesised compression actually be?

If we're talking Billions of years...that's one thing, if it's on the order of a few years, that's another entirely.

Do quark stars emit light? And by what mechanism.

Hello wilder. They sure do. Through a mechanism called Bremsstrahlung radiation. I read a great paper about it from the University of Vancouver I will try to find it on my pc tonight. Although the emmissivity of photons is very small they still emit a small amount of light when bending of electron trajectories occur in the electrosphere of the Quark Star.
