Quark (dairy product) a somewhat crumbly texture (like ricotta). The basic quark this basic quark or skimmed quark ("Magerquark") must under German Law have less than 10% fat by dry mass. Quark with higher fat content is made by adding cream after cooling. It has a very smooth and creamy texture and is slightly sweet (unlike sour cream). A firmer version called "Schichtkäse" (layer cheese) is often used for baking. Schichtkäse is distinguished from quark by having an added layer of cream sandwiched between two layers of quark. Quark is also often sold flavored with herbs, spices, or fruit. In general, dry mass
Quark star so far to explore most properties of quark matter, the exact conditions and nature of quark stars, and their existence, remain hypothetical and unproven. The question whether such stars exist and their exact structure and behavior is actively studied within astrophysics and particle physics. If they exist, quark stars would resemble and be easily mistaken for neutron stars: they would form in the death of a massive star in a Type II supernova, they would be extremely dense and small, and possess a very high gravitational field. They would also lack some features of neutron stars, unless they also contained
