How many types of dwarf stars are there?

A dwarf star generally refers to any main-sequence star, a star of luminosity class V: main-sequence stars (dwarfs). Red dwarfs are low-mass main-sequence stars; yellow dwarfs are main-sequence (dwarf) stars with masses comparable to that of the sun and orange dwarfs are K-type main-sequence stars.

A blue dwarf is a hypothesized class of very-low-mass stars that increase in temperature as they near the end of their main-sequence lifetime, while a white dwarf is a star composed of electron-degenerate matter, known to be the final stage in the evolution of stars not massive enough to collapse into a neutron star or black hole—stars less massive than roughly nine solar masses.

A black dwarf is a white dwarf that has cooled sufficiently such that it no longer emits any visible light while a brown dwarf is a sub stellar object not massive enough to ever fuse hydrogen into helium, but still massive enough to fuse deuterium. That's less than about 0.08 solar masses and more than about thirteen Jupiter masses.

There are different types of dwarf stars that are available. It is only fitting that you would know the different types. The main dwarf types are 7. These are the following types: red dwarf, yellow dwarf, orange dwarf, blue dwarf, white dwarf, black dwarf, and white dwarf.

The dwarf stars usually start out as the red dwarf star as time goes on and the star loses its energy, it changes color depending on the life stage that it is currently in. People should remember that dwarf stars are still massive in size even when compared to other planets.
