How much smaller is a white dwarf compared to its main sequence size?
A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.
Why would a supergiant have a brighter absolute magintude than a white dwarf?
A supergiant is much larger than a white dwarf. A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.
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 typical size of the typical white dwarf in solar radii?
The typical size of a white dwarf is about the size of Earth, which is approximately 0.008 solar radii. White dwarfs are very dense objects that have collapsed from the remnants of low to medium mass stars.
How large is a white dwarf?
A white dwarf is typically about the size of Earth, but with a mass comparable to that of the Sun. This means it is extremely dense, packing a lot of mass into a small volume.
Is a white dwarf star about the size of a city?
No, a typical white dwarf star is roughly the size of the Earth.
What happens to the size of a white dwarf when its mass is increased?
When the mass of a white dwarf increases, its size decreases. This is because the increased mass causes the white dwarf to contract under its own gravity, making it smaller and denser.
How much smaller is a white dwarf compared to its main sequence size?
A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.
Why would a supergiant have a brighter absolute magintude than a white dwarf?
A supergiant is much larger than a white dwarf. A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.
Is it true or fault that A white dwarf star is about the same size as the sun?
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
How large is a black dwarf?
The same size as the white dwarf it was. See related question.
How does the the mass and size of a white dwarf compare with the mass and size of the sun?
A white dwarf, also called a degenerate dwarf, is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth.
Is the Sun a white dwarf before becoming its present size?
No. In about 7.5 billion years the Sun will become a white dwarf.
What is the size of a white dwarf compared to?
A white dwarf has the approximate diameter of a moon, or a small planet.
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.
Is a white dwarf considered large or small?
A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
What is the typical size of the typical white dwarf in solar radii?
The typical size of a white dwarf is about the size of Earth, which is approximately 0.008 solar radii. White dwarfs are very dense objects that have collapsed from the remnants of low to medium mass stars.
