How is degeneracy pressure related to white dwarfs and neutron stars?
Wiki User
∙ 8y ago
White dwarfs are prevented from collapsing further by electron degeneracy pressure. If the mass of a stellar remnant exceeds the Chandrasekhar limit, about 1.4 solar masses, gravity will overcome this pressure and form a much smaller and denser neutron star. Further collapse in a neutron star is prevented by neutron degeneracy pressure up until the Tolman-Oppenheimer-Volkoff limit of about 3 solar masses, at which point gravity causes a complete collapse, forming a black hole.

Why do white dwarfs not continue to contract as they cool?
White dwarfs do not contract because the electron degeneracy pressure is stronger than gravity for stars with masses like white dwarfs. It holds them apart.
What do white dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
What is a small hot very dense star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
What is degenerate matter?
Degenerate matter is extremely dense matter with characteristics governed by quantum mechanics. One of the notable traits is that temperature and pressure are independent of one another. Two forms of matter known to exist are electron degenerate matter, which comprises white dwarfs, and neutron degenerate matter, which comprises neutron stars.
What is the difference between star that become white dwarfs and stars that become neutron stars?
the simple reson is mass.......that is if the star under consideration is a heavy one, it is more likely to turn into a black hole and if it is comparatively smaller it is prone to turn into a neutron star or a white dwarf
Is this true or false brown dwarfs white dwarfs and neutron stars are all kept from collapsing by degeneracy pressure?
True.

What has the author Dongsu Kyu written?
Dongsu Kyu has written: 'Neutron stars and white dwarfs in galactic halos?' -- subject(s): White dwarfs, Neutron stars
What is the diffrance between stars that become white dwarfs and stars that become neutron stars?
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
What are the smallest stars?
The smallest stars are called neutron stars.They typically have a diameter of only 12kmthe smallest star is the neutron star from the word "neutron"
What stars have the highest densities?
Black holes, neutron stars, and the white dwarfs
What is a Very small hot star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
What is a small hot very dense star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
Explain why the sun does not collapse under the force of its own gravity?
Stars do not collapse because the inward force of gravity is balanced by the pressure generated by fusion. When stars die they do collapse. The cores of low to medium mass stars collapse to form white dwarfs. Further collapse is prevented y electron degeneracy pressure. More massive stars leave behind neutron stars, in which gravity is balanced by neutron degeneracy pressure. In the most massive stars, once fusion stops producing energy there is nothing to stop the collapse and the core becomes a black hole.
What ordinarily keeps a star from collapsing?
Further collapse is prevented by electron degeneracy pressure.
