Quark (dairy product) manufactured by "Dairyland". Quark may also be available as "baking cheese", "pressed cottage cheese", or "fromage frais". In Australia, Ukrainian traditional quark is produced by Blue Bay Cheese in Mornington Peninsula. It is also sometimes available from supermarkets labelled as quark or quarg. In New Zealand, European traditional Kwark is produced by Karikaas in North Canterbury. It is available in 350g pots and available online and in speciality stores such as Moore Wilsons. In the United Kingdom, fat-free quark is produced by several independent manufacturers based throughout the country. All the big four supermarkets in the UK sell their own
Quark star a shell of neutron matter, because free quarks are not expected to have properties matching degenerate neutron matter. For example, they might be radio-silent, or not have typical size, electromagnetic, or temperature measurements, compared to other neutron stars. The hypothesis about quark stars was first proposed in 1965 by Soviet physicists D. D. Ivanenko and D. F. Kurdgelaidze. Their existence has not been confirmed. The equation of state of quark matter is uncertain, as is the transition point between neutron-degenerate matter and quark matter. Theoretical uncertainties have precluded making predictions from first principles. Experimentally, the behaviour of quark matter is
