quark star

A hypothetical celestial object that is the remnant of a massive star that has collapsed with a force sufficient to reduce all particles to strange quarks. Also called strange star.

quark star

A superdense celestial object that is formed when the remnants of old stars collapse on themselves, denser than a neutron star but not dense enough to become a black hole. Quark stars were first hypothesized in the 1980s, but the first was not discovered until early 2002. Like neutron stars, quark stars are composed of neutrons that have undergone enough pressure by the collapse of the star to have lost their differentiation and dissolved into a mass of quarks and gluons. The up and down quarks of which neutrons are composed then change into strange quarks, with the resulting strange matter compacting into an even denser mass than a neutron star. Also called strange star.

strange matter strange star			A resulting quark star, for example, would consist of up and down quarks, which make up protons and neutrons, and also strange quarks, which are heavier and not found in ordinary matter. Just neutrons, no quarks. (Neutron Star Stuff) by Cowen, R. / Science News A quark star would consist entirely of the building blocks of matter called quarks, but they wouldn't be combined into more massive particles, as they are in all matter known to date. Strange Stars? Odd features hint at novel matter. (This Week) by Weiss, P. / Science News The quark nuggets would be produced in a charged form and accelrated by electromagnetic fields near the quark star and then neutralized on the way.
