If you are in the northern hemisphere, Winter is a good time to see Orion. Using Orions belt as pointer stars, continue down to the horizon and you'll see a very bright star - Sirius. It's the brightest star in out skies due to its actual brightness and its close proximity to our solar system (8 light years or so).
It is actually a binary star system though, there are two stars in orbit about each other. The main star, Sirius A is a white hot main sequence star (active), while its companion, Sirius B, is a white dwarf star. Sirius B was thought to once be the most massive of the two, but became an inactive white dwarf some 120 million years ago. Online pictures will show the two stars side by side, the Sirius B white dwarf seen as a much smaller and dimmer star than its active companion, Sirius A. You wont be able to pick out the two stars with the naked eye.
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
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.
No. A white dwarf is the remnant of a low to medium mass star.
A white dwarf is much larger than a neutron star.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
No a white dwarf is a small compact star.

A white dwarf star's temperature can range from approximately 7000K to 19000K.
No, a typical white dwarf star is roughly the size of the Earth.

white dwarf star
That might be a white dwarf.
