A dwarf star could form in different ways depending on what kind. Red dwarfs and brown dwarfs are formed when nebula compresses into a giant burning ball of gas, just like most stars do; white dwarfs are formed after a star became a red giant and blown off its outer layers, the remaining core became a white dwarf; black dwarfs are formed after white dwarfs cooled down and stopped emitting visible light.
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
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
a white dwarf
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
If it is small and cool enough it could be a "brown dwarf". If it is a little warmer it is called a "Red Dwarf".
the sun is NOT a dwarf star, it is a g-type star. a dwarf is a s-type starThe Sun is a G2V star G2 means the second hottest of the yellow G class and V (the Roman numeral five) identifies the Sun as a main sequence DWARF STAR (so yes it is a dwarf star) A star with spectral S is a late-type giant star (similar to class K5-M).
