Is a white dwarf capable of fusing elements?
Not normally. A white dwarf is the remnant of a star in which fusion has stopped. If, however, a white dwarf has a close binary companion star it can accrete gas from that companion. If enough gas collects on the white dwarf it can ignite a complex reaction change between the hydrogen gas and the carbon, nitrogen, and oxygen of the surface. Unlike the steady fusion in a main sequence star, the fusion on a white dwarf is a runaway reaction that results in a massive explosion called a nova, which drives away the accreted gas and ends fusion. If the white dwarf is massive enough the accretion of gas can trigger carbon fusion inside the white dwarf, resulting in an even larger explosion called a type Ia supernova, which destroys the white dwarf.
Why would white dwarf stars have less amount hydrogen?
A white dwarf is the remnant of a star that has fused all the hydrogen and helium in its core, leaving mostly carbon and oxygen nuclei.
What will the white dwarf that remains when our sun dies will be mostly made of?
When our Sun dies, it will shed its outer layers, leaving behind a white dwarf primarily composed of carbon and oxygen. This is a result of the fusion processes that occurred during its lifetime, where hydrogen was converted into helium, and later, helium into carbon and oxygen in its core. The white dwarf will no longer undergo fusion and will gradually cool down over time.
What type of stars has a low temperature and high luminosity?
A white dwarf.A white dwarf.A white dwarf.A white dwarf.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
What changes are happing during the life cycle of a white dwarf?
The white dwarf will cool down till it becomes a black dwarf. If it's part of a close binary with a main sequence, giant or supergiant, the white dwarf can gain mass from the other star. This can start fusion of carbon in the white dwarf. Other fusion reactions quickly follow, causing it to explode. This is known as type 1a supernova.
Is a dwarf star and a white dwarf the same thing?
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
Does a white dwarf turn into a diamond?
White dwarfs are composed mostly of carbon and oxygen, but they do not turn into diamonds. The intense pressure in the core of a white dwarf prevents the carbon from forming into the crystalline structure of a diamond.
Is white sugar a element?
No, white sugar is not an element. White sugar is a compound made up of carbon, hydrogen, and oxygen atoms.

What is final core element for a solar like star?
The final elements fused in a star of the mass of our Sun are Oxygen then Carbon. Therefore a white dwarf core could be regarded as a solid, gigantic diamond.
Why would white dwarf stars have less amount hydrogen?
A white dwarf is the remnant of a star that has fused all the hydrogen and helium in its core, leaving mostly carbon and oxygen nuclei.
What happens if the mass of a white dwarf reaches the 1.4 solar mass limit?
If the mass of a white dwarf reaches the 1.4 solar mass limit, it will no longer be able to support itself against gravity through electron degeneracy pressure. This will trigger a runaway fusion reaction of carbon and oxygen, leading to a supernova explosion known as a Type Ia supernova.
When the outer envelope of a red giant recedes the remaining carbon core is called?
When the outer envelope of a red giant recedes, the remaining carbon core is called a white dwarf. This core is extremely hot and dense, with no nuclear fusion taking place.
When a star has no fuel left and its outer layers escape into space what is its remaining core called?
When the layers escape into space, this is classified as a planetary nebula. What usually is left behind is a white dwarf.
What will the white dwarf that remains when our sun dies will be mostly made of?
When our Sun dies, it will shed its outer layers, leaving behind a white dwarf primarily composed of carbon and oxygen. This is a result of the fusion processes that occurred during its lifetime, where hydrogen was converted into helium, and later, helium into carbon and oxygen in its core. The white dwarf will no longer undergo fusion and will gradually cool down over time.
What can cause a white dwarf to reignite?
The most likely way to reignite fusion in a white dwarf is for gas from a close binary companion to be pulled to it by gravity. As the gas collects the white dwarf heats up and may either ignite fusion in the hydrogen or in the carbon of the white dwarf itself.
