thermodynamics - What is the core temperature of neutron star as a ...
3 I wish to know about the temperature of the bulk (not just the surface) of a neutron star. I am especially interested in the highest temperature part which I assume is the core, but would want to know how much of the star that is. I mainly want to know about the early part (thousands of years) after formation, but any information would be ...
How do neutron stars overcome neutron degeneracy? - Physics Stack Exchange
Neutron stars and General Relativity In neutron stars, the reason for the upper limit is also because hydrostatic equilibrium cannot be reached, either because of the increasing density (even if the neutrons remain intact) but possibly accelerated if the neutrons are removed.
Why do neutron stars have such powerful magnetic fields?
The magnetic strength of these objects is too low based on flux conservation from the original star and yet too high for a composition of mainly neutrons. Is it actually due to some quantum effect?
Position of Neutron Stars in H R diagrams - Physics Stack Exchange
This is fine that neutron star cools of with time but knowing the teperature and radius, luminous can be determined. SO why can't we define a region which includes both the young (hot) and old (cool) neutron stars? It evolves , not changes it properties abruptly. So there can be a continuous region for neutron stars in H R diangrams.
Why is the least massive neutron star less massive than the most ...
That is because the main pathway to create a neutron star is a core collapse supernova. This is triggered by an instability (caused by photodisintegration or electron capture) that occur as the electron-degenerate iron core accretes mass and approaches its Chandrasekhar limit. The Chandrasekhar mass is composition dependent.
mass - What would happen to a teaspoon of neutron star material if ...
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 numbers. The protons and leptons would make neutron-rich elements like deuterium, but most of the matter would consist of free neutrons.
Are black holes neutron stars with more mass?
8 As we know, a star that is too massive to become a white dwarf becomes either a neutron star or if it is even more massive, a black hole: neutron stars form with great gravity that comes with great mass, the gravity pushing down on its core, merging protons and electrons into neutrons making the core consist only of neutrons.
astrophysics - What is the theoretical lower mass limit for a ...
But, I think this is not the smallest possible neutron star mass - it is only the smallest mass that can be produced by stellar evolution processes. For example, black holes have also a lower limit: the Tolman-Oppenheimer-Volkoff limit, which is around 1.5-3.0 Solar masses.
Mining a neutron star -- what do you get? - Physics Stack Exchange
The neutron star matter is a good model of what the universe looked like in the first few micoseconds after the Big Bang, just after the baryogenesis. The neutrons in a neutron star are kept from decaying by the degenerate electron gas (both neutrons and electrons, as well as protons at some depth and below, are degenerate in a neutron star).
What is the pressure and density of a neutron star?
I am interested in finding pressure of neutron star! So. Please could any tell me how to choose central density for the inner and outer core of neutron Star. What numeric value should me in both c...
