Is Earth's iron core kind of like a white dwarf?
Because Earth's iron core has iron atoms not bonded to one another but in a lattice where there is a sea of electrons and there are ionized iron atoms holding back from gravitational collapse of the ...

Mass formation of a neutron star Vs White dwarf
I have been researching the different outcomes of a star's death. I understand that the main factor is the star's mass at the end of its life, along with others such as its metallicity. Well, the ...

Luminosity and absolute magnitude relationship
Context : an exercise gives the temperature, mass, distance and apparent magnitude of Sirius B and asks to calculate its density.
One key step of the calculation is to get the luminosity from the ...

Massive star evolution leading to white dwarf?
Is it possible that a star with an initial mass greater than $12 M_\odot$ loses so much mass in the giant phase that it eventually becomes a white dwarf? If it is possible, what constellation or ...

Does the wave function of localized s-orbitals radius reduce under extreme solid-state pressures prior to degeneracy?
Under extreme conditions not found in nature, say low temperature solids that are under extreme pressures* prior to collapse into degenerate matter states, does a localized s-orbital radius reduce ...

Paradox about white dwarfs and ionization
I am facing a dilemma. The fact that matter is ionized allows ions and electrons to be much closer together than they are in atoms (Bohr radius $a = 0.5 \cdot 10^{− 10} \mathrm{m}$), and the result is ...

Modelling a fully relativistic White Dwarf Star
I am trying to model a fully relativistic white dwarf using different central densities. Using the below equations:
$\frac{dP}{dm} = -\frac{Gm}{4\pi r^4}$
$\frac{dr}{dm} = -\frac{1}{4\pi\rho r^2}$
and ...
