After a planetary nebula occurs, the core of the star collapses and becomes a white dwarf. This white dwarf slowly cools down over billions of years until it eventually becomes a cold, dark remnant known as a black dwarf.
after a nova star becomes bright it turns into a dwarf and explodes.
its original mass when it formed
When a white dwarf star no longer emits energy, it becomes a black dwarf. Black dwarfs are theoretical end points of stellar evolution where all nuclear reactions have ceased, and the star has cooled down to the background temperature of the universe.
It is dead. It becomes a black dwarf, just a rock.
In that case, it will basically stop emitting any radiation. No star has had time so far to become a black dwarf - the Universe is too young for that. This is because it takes a white dwarf a long, long time to cool down.
Yes, a mid-sized star can eventually become a white dwarf or a black dwarf. After exhausting its nuclear fuel, the star sheds its outer layers to form a planetary nebula, leaving behind a white dwarf. Over trillions of years, a white dwarf may cool and fade into a black dwarf, although this process would take longer than the current age of the universe.
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
The sun enrgey goes in the white dwarf and the sun becomes a giant bright star then it is.
a supernova, and that's not a "death", because it becomes a black dwarf (it is still a star, but it doesn't shine because it doesn't have any gases to burn anymore)Answera supernova, and that's not a "death", because it becomes a black dwarf (it is still a star, but it doesn't shine because it doesn't have any gases to burn anymore)
