This answer is partially correct. White dwarf stars are what happens when a normal Sun-sized star has reached the end of its life."
However, we need not give up hope that a white dwarf could still end its life with some fireworks. "White dwarf stars do not become supernovas. ... -type II supernova ... -A white dwarf that has accumulated too much mass from binary companion. This rebound of matter is thought to be the supernova. A supernova is the explosion of a star -- the largest explosion that takes place in space.
In this type of supernova, a white dwarf in a binary star system gains mass from its companion. White dwarfs are still stars, after all, and in principle they can be reignited.
What happens to a star after the red-giant phase is not certain.
A white dwarf in a close binary system will explode as a supernova if it gains enough mass to exceed the __ white dwarf limit (1.4 solar masses). We do know that a star, regardless of its size, must eventually run out of fuel and collapse. White Dwarf Limit - white dwarfs cannot exceed 1.4 solar masses, electron degeneracy pressure can no longer resist gravity and thus it collapses How does a white dwarf supernova happen?
It condenses into a neutron star and ejects matter outward.
White dwarf reaches 1.4 solar masses (through accretion) and explodes into a supernova White dwarf stars are what happens when a normal Sun-sized star has reached the end of its life." The core of the star is left with increased temperature and pressure.
Browse. In such a system one of the stars is a white dwarf, a small, dense star near the end of its nuclear burning phase. Start studying Stellar Explosions.
White dwarf stars are the corpses of stars; what happens once they’ve used up all their fuel and lack the temperature and pressure to continue fusion in their core. As its mass increases, the temperature and pressure within the white dwarf also increase, until nuclear fusion re-ignites at its center. Search. Because of this, the limit is never achieved. Most supernovas, meanwhile, mark the deaths of massive stars and the formation of neutron stars. As a star's evolution approaches the Type II supernova, we find photo disintegration of iron nuclei begins at 10 billion K to ignite the supernova. They are triggered when a shockwave tears through the outer layers of a … In the case of the type Ia supernova, a white dwarf in a slowly-rotating binary system (composed of two stars) can get more mass from its pair. This answer is partially correct.
The white dwarf will explode completely as a white dwarf supernova.
