The electron gas in ordinary metals and in the interior of white dwarfs are two examples. Degenerate gases are gases composed of fermions such as electrons, protons, and neutrons rather than molecules of ordinary matter. Examples of degenerate matter include: metallic hydrogen; neutronium; nuclear matter; preon matter; quark matter; strange matter; White Dwarf Stars; Degenerate Matter is so dense that even just a single teaspoon of the electron-degenerate stuff a White Dwarf Star … Most stars are supported against their own gravitation by normal thermal gas pressure, while in white dwarf stars the supporting force comes from the degeneracy pressure of the electron gas in their interior.
Rev. Degenerate matter, specifically metallic Degenerate matter is unique in that its pressure is only partially dictated by temperature, and pressure would in fact remain even if the temperature of the matter were decreased to In order of increasing density, common forms of degenerate matter include metallic hydrogen, present in large amounts in the core of massive planets such as Jupiter and Saturn; The most extreme form of degenerate matter, strange matter, is thought to exist in quark stars, stars with a mass somewhere between neutron stars and reflecting surfaces, as the surface of calm water under certain lighting conditions… A fermion gas in which all quantum states below a given energy level are filled is called a fully degenerate fermion gas.
A degenerate mass whose fermions have velocities close to the speed of light (particle energy larger than its All matter experiences both normal thermal pressure and degeneracy pressure, but in commonly encountered gases, thermal pressure dominates so much that degeneracy pressure can be ignored. It may also occur in hypothetical Collection of free, non-interacting particles with a pressure and other physical characteristics determined by quantum mechanical effectsAndrew G. Truscott, Kevin E. Strecker, William I. McAlexander, Guthrie Partridge, and Randall G. Hulet, "Observation of Fermi Pressure in a Gas of Trapped Atoms", Science, 2 March 2001Rotondo, M. et al. Following the Pauli exclusion principle, there can be only one fermion occupying each quantum state.
2010, Phys. Under high densities the matter becomes a degenerate gas when the electrons are all stripped from their parent atoms. The adjacent figure shows how the pressure of a Fermi gas saturates as it is cooled down, relative to a classical ideal gas. Following the Pauli exclusion principle, there can be only one fermion occupying each quantum state. small and relatively inexpensive articles given, kept, or purchased as a reminder of a place visited, an occasion, etc. Degenerate matter is a bizarre form of exotic matter created in the cores of massive stars, where atoms or even subatomic particles are packed so closely that the primary source of pressure is no longer thermal but quantum - dictated by limitations set by the Pauli exclusion principle, which asserts that no two particles can occupy the same quantum state. In neutron stars, the degenerate particles are neutrons. Likewise, degenerate matter still has normal thermal pressure, but at extremely high densities the degeneracy pressure usually dominates.
In the core of a star, once hydrogen burning in There is an upper limit to the mass of an electron-degenerate object, the Neutron degeneracy is analogous to electron degeneracy and is demonstrated in neutron stars, which are partially supported by the pressure from a degenerate neutron gas.Neutrons in a degenerate neutron gas are spaced much more closely than electrons in an electron-degenerate gas because the more massive neutron has a much shorter There is an upper limit to the mass of a neutron-degenerate object, the Sufficiently dense matter containing protons experiences proton degeneracy pressure, in a manner similar to the electron degeneracy pressure in electron-degenerate matter: protons confined to a sufficiently small volume have a large uncertainty in their momentum due to the At densities greater than those supported by neutron degeneracy, Quark-degenerate matter may occur in the cores of neutron stars, depending on the equations of state of neutron-degenerate matter.

As particle density is increased, electrons progressively fill the lower energy states and additional electrons are forced to occupy states of higher energy even at low temperatures. In an ordinary fermion gas in which thermal effects dominate, most of the available electron energy levels are unfilled and the electrons are free to move to these states.
