A white dwarf's mass is comparable to that of the Sun while its volume is comparable to that of the Earth.
The Sun is 100 times larger than the Earth, so a white dwarf has a mass 100 times greater than the Earth.
The maximum size of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. If a white dwarf exceeds this limit, it can collapse further and ignite as a supernova.
It is true that a white dwarf above about 1.4 solar masses cannot exist. When a star dies, most of the mass does not become part of the remnant. A star 5 times the mass of the sun will shed most of its mass during the red giant phase. Only the innermost portion will collapse to form a white dwarf.
No. It does not have enough mass. Only stars 8 times the mass of the sun or greater can become pulsars. The sun will become a white dwarf.
Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.
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.
The upper limit to the mass of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. Beyond this point, the white dwarf may collapse and explode in a supernova event.

The maximum size of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. If a white dwarf exceeds this limit, it can collapse further and ignite as a supernova.
It is true that a white dwarf above about 1.4 solar masses cannot exist. When a star dies, most of the mass does not become part of the remnant. A star 5 times the mass of the sun will shed most of its mass during the red giant phase. Only the innermost portion will collapse to form a white dwarf.
A white dwarf is the remnant of a low to medium mass star.
A Chandrasekhar mass is the maximum mass limit (about 1.4 times the mass of the Sun) that a white dwarf star can have before it collapses under its own gravity and triggers a supernova explosion. When a white dwarf accretes matter from a companion star or merges with another white dwarf, exceeding the Chandrasekhar mass, it can collapse and explode as a Type Ia supernova.
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.
If a white dwarf gained enough mass to reach the 1.4 solar-mass white dwarf limit, it would undergo a catastrophic event known as a Type Ia supernova. This explosion would release a tremendous amount of energy and result in the complete destruction of the white dwarf.
Several times smaller than our Sun. Details vary, depending on the type of dwarf star (a red dwarf and a white dwarf are quite different things), and the exact mass.
No. A white dwarf is the remnant of a low to medium mass star.
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.
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.
