The maximum mass of ideal white dwarfs
Splet04. jan. 2014 · The mass-radius relations for white dwarf stars are investigated by solving the Newtonian as well as Tolman-Oppenheimer-Volkoff (TOV) equations for hydrostatic equilibrium assuming the electron gas to be non-interacting. We find that the Newtonian limiting mass of is modified to in the general relativistic case for He (and C) white dwarf … Splet31. maj 2024 · According to ProfRob's answer to it, it probably lies somewhere between 0.087 and 0.19 solar masses (computations differ, but this gives us an order of …

Splet01. sep. 2016 · It is then argued that the maximum mass of such an ideal white dwarf tends to infinity, as opposed to the conventional case where it has a finite value. Discover the … SpletThe maximum mass of ideal white dwarfs. The theory of thepolytropic gas spheres in conjunction with the equation of state of arelativislically degenerate electrongas leads to aunique value for the mass of a star built on this model. This mass (=0.9I⊙) is interpreted as representing the upper limit to the mass of an ideal white dwarf.
Splet13. okt. 2016 · We perform an extensive stability analysis of such objects, with their highest surface magnetic fields reaching $\sim 10^{13}~G$ (at which point the star adopts a … SpletTaking up to date values for the mass, radius and temperature of Sirius B from Holberg et al. [1998] we can infer some basic properties of the interior of white dwarf stars in general. It should be noted that Sirius B is not particularly representative of white dwarf stars, being of considerably higher mass, and is chosen more for historical ...
SpletA degenerate mass whose fermions have velocities close to the speed of light ... In the case of neutron stars and white dwarfs, this phenomenon is compounded by the fact that the pressures within neutron stars are much higher than those in white dwarfs. ... The theoretical limit for non-relativistic objects supported by ideal neutron degeneracy ... The Chandrasekhar limit is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M☉ (2.765×10 kg). White dwarfs resist gravitational collapse primarily through electron degeneracy pressure, compared to main sequence stars, which resist collapse through thermal pressure. The Chandrasekhar limit is the mass above which electron degeneracy pressure in the star's core is i…
Splet19. jan. 2012 · The Chandrasekhar Limit is therefore not just as upper limit to the maximum mass of an ideal white dwarf, but also a threshold. A star surpassing this threshold no …
SpletThe Chandrasekhar limit is the maximum mass of a stable white dwarf star. The limit was first published by Wilhelm Anderson and E. C. Stoner, and was named after Subrahmanyan Chandrasekhar, the Indian-American astrophysicist who improved upon the accuracy of the calculation in 1930, at the age of 19. how to make a 2 way shot creator 2k22Splet24. sep. 2024 · It is shown that near the maximum mass the mass of hot rotating white dwarfs is slightly less than for cold rotating white dwarfs, though for static white dwarfs the situation is opposite.
