Position of Neutron Stars in H R diagrams - Physics Stack Exchange
May 20, 2022 · The HR diagram is an observational diagram.Whilst neutron stars could be placed in the HR diagram in the same way as white dwarf stars are, it turns out to be impractical to do …
How do neutron stars burn? Is it decay or fusion or something else?
Some argue that the core of a neutron star, due to its high density, might be an ideal place for this phase transition to happen. So in short, the neutron star could "burn" into a quark star and …
astrophysics - What is the theoretical lower mass limit for a ...
Oct 26, 2014 · We think that most neutron stars are produced in the cores of massive stars and result from the collapse of a core that is already at a mass of $\sim 1.1-1.2 M_{\odot}$ and so …
Neutron stars and black holes - Physics Stack Exchange
The neutron star contains nucleons (neutrons and protons) that are packed to the maximum density possible in the Universe. The density of a neutron star is 3.7x10^17 to 5.9x10^17 …
mass - What would happen to a teaspoon of neutron star material …
Dec 4, 2014 · It is difficult to describe what it would inflate out into - the neutron star material can be imagined as an incredibly dense soup of neutrons with some protons and leptons in small …
Are black holes neutron stars with more mass?
Oct 16, 2023 · If black hole formation by the simple addition of more mass to a neutron star was common, then we might expect to see many more objects populating the mass range just …
gravity - How do neutron stars overcome neutron degeneracy?
Feb 22, 2024 · If the star is heavy enough, the protons in the star will capture electrons, forming neutrons and bypassing the exclusion principle for electrons. The exclusion principle can come …
How do neutron stars emit black body radiation?
Dec 9, 2020 · $\begingroup$ Neutron stars have a charged components (mostly protons and electrons). For pure neutron matter, it is possible to consider non-minimal coupling of the …
Is the speed of sound almost as high as the speed of light in …
The neutron star crust is a solid and there are indeed elastic waves for which the speed of sound is controlled by the shear modulus.
Upper limit of neutron star mass and collapse to a black hole
Jan 12, 2021 · For your more precise question, the upper bound to a non-rotating neutron star is the Tolman-Oppenheimer-Volkoff limit, which is between 2.1 to 2.3 solar masses. Beyond this, …
