White Dwarf, Sun, Red Giant, Supernova
A white dwarf is several hundred billion times denser than the average density of the sun.
A stars evolution. Our Sun will go yellow dwarf -> red giant -> white dwarf -> black dwarf.
In 5 billion years time, our Sun will turn into a white dwarf.
NO.
A white dwarf
The sun is neither a supernova nor a white dwarf. The sun is a main sequence star. A supernova is not a kind of star: it is the explosion of a massive star.
A white dwarf is the death of a medium sized star - similar to our own Sun.
A white dwarf cooking into a black dwarf
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.
No. It will become a white dwarf in about 7.5 billion years time.
