Degenerate Gas
A state of matter found in white dwarfs and other ultrahigh-density objects, in which the electrons follow Fermi-Dirac statistics.
Degenerate Gas - A gas in which a type of particle (electrons or neutrons) are as tightly packed as permitted by the Pauli exclusion principle. In a degenerate gas, temperature has essentially no influence on pressure ...
Degenerate gas is a particular configuration, usually reached at high densities, of a gas composed of subatomic particles with half-integral intrinsic angular momentum (spin).
DEGENERATE GAS
A degenerate gas is one that is super-compressed and very dense. The molecules of this degenerate gas are virtually touching one another and the gas acts much like a solid.
degenerate gas - (n.)
A gas in which either free electrons or free neutrons are as densely spaced as allowed by laws of quantum mechanics.
A degenerate gas in which the densities are so great that the nuclei are fixed with respect to each other so that they resemble a crystalline lattice. [H76]
Quantum Space ...
degenerate gas super-compressed gas that behaves more like a solid and whose properties must be described by quantum mechanics. The pressure of degenerate gas does not depend on the temperature.
Once the temperature is hot enough for helium fusion in one part of the core, the reaction quickly spreads throughout it due to the behaviour of the electron degenerate gas, the whole process taking minutes or hours.
In an X-ray burster, this hydrogen-rich material accretes onto the surface of the neutron star as a layer of degenerate gas. After enough of this material accumulates, fusion ignites in the degenerate gas.
Can you explain the concept of degenerate gas pressure?
...and Other Types of Stars
What are the different types of stars?
Matter can exist in four phases (solid, liquid, gas, and plasma) and a few other extreme phases, like critical fluids and degenerate gases. The phase diagram of water (above) shows its phase at various temperatures and pressures.
