What else can I help you with?
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
What is the relationship between a black dwarf and a white dwarf?
A black dwarf is a theoretical end-stage of a white dwarf star in the far future, after it has cooled down and no longer emits light. White dwarfs are hot, dense remnants of low to medium mass stars at the end of their evolution.
Which is bigger a galaxy or a white dwarf star?
A galaxy is much larger than a white dwarf star. Galaxies can contain billions to trillions of stars, along with gas, dust, and dark matter, and can measure thousands of light-years across. In comparison, a white dwarf star is a small, dense remnant of a star that is roughly the size of Earth but with a mass similar to that of the Sun.
What is the smalist star?
The smallest star in the universe is a Red Dwarf.
How far from earth is the star Adhil?
It is 196 light years far from the earth. In fact Adhil(Arabic name) is a binary star in the Andromeda constellation.
How far away is the dwarf star from earth?
The nearest dwarf star is Proxima Centauri, about 4.24 light years away and so dim it can't be seen in binoculars.
What is the cycle of the black dwarf star?
There are no "cycles". A black dwarf star is the final stage of a white dwarf - a white dwarf that has cooled down so much that it no longer emits significant amounts of radiation. The Universe is currently too young to have black dwarves; white dwarves are expected to become black dwarves in the far future.
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
When a star becomes a black dwarf it?
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.
Does a red dwarf generate a lot of energy?
It depends on what you consider to be a lot of energy. A red dwarf generates far less energy than other classes of star, but still far more than anything on Earth.
What is old cold star?
That means that it's a start, that it's old, and that it's cold.Basically it might refer to a black dwarf - a hypothetical star that doesn't exist yet, but which it is assumed will exist in the far future - a white dwarf that has cooled down.
What is the relationship between a black dwarf and a white dwarf?
A black dwarf is a theoretical end-stage of a white dwarf star in the far future, after it has cooled down and no longer emits light. White dwarfs are hot, dense remnants of low to medium mass stars at the end of their evolution.
When will Sirius the star become a Black Dwarf?
Sirius, the brightest star in the night sky, is a binary system consisting of Sirius A and Sirius B. Sirius B, which is a white dwarf, will eventually cool and fade into a black dwarf over an estimated timeframe of trillions of years. However, the universe is not old enough for any black dwarfs to currently exist, including Sirius B. Therefore, Sirius A and B will not become a black dwarf for billions of years, far beyond the current age of the universe.
Which is bigger a galaxy or a white dwarf star?
A galaxy is much larger than a white dwarf star. Galaxies can contain billions to trillions of stars, along with gas, dust, and dark matter, and can measure thousands of light-years across. In comparison, a white dwarf star is a small, dense remnant of a star that is roughly the size of Earth but with a mass similar to that of the Sun.
What prevents a black dwarf star from shrinking indefinitely?
It is believed that black dwawfs are the burnt out hulks of white dwarfs. In its dying phase a star 1.5 solar masses or less will shrink to something around the size of the Earth, and there is no more nuclear fusion taking place , but heat remaining will make it continue to shine for several billion years. It can only shrink so far because of electron degeneracy, a condition where the electron repulsion stops them from being pushed any closer together.It will not shrink further as a black dwarf.
How far is the wolf 359 from the earth?
Wolf 359 is a tiny red dwarf star 7.8 light-years away. At magnitude 13, it is not visible in hobbyist-class telescopes.
What is the smalist star?
The smallest star in the universe is a Red Dwarf.
