People also ask, what happens if a white dwarf exceeds the Chandrasekhar limit?
3 Answers. The Chandrasekhar limit is the maximum mass of a stable white dwarf star. White dwarfs with masses greater than the limit undergo further gravitational collapse, evolving into a different type of stellar remnant, such as a neutron star or black hole.
Furthermore, what happens as the mass of a white dwarf increases? For normal stars, if you increase the mass, the star gets larger, its radius increases. However, for white dwarfs, the opposite is true, increasing the mass shrinks the star. Notice that at some mass the radius of the star goes to zero.
Thereof, what is the mass limit of a white dwarf?
The Chandrasekhar Limit of 1.4 solar masses, is the theoretical maximum mass a white dwarf star can have and still remain a white dwarf (though this limit does vary slightly depending on the metallicity).
What happens when a white dwarf becomes larger than 1.4 solar masses?
A white dwarf star is in balance between gravity and degeneracy pressure, but if the mass is too large (greater than 1.4 solar masses, called the Chandrasekhar limit), the degeneracy pressure is not adequate to hold up the star, and the star collapses. The white dwarf then collapses.
