Red dwarf stars are the commonest stars, at least in the region of space around our Sun.
There are many red dwarf stars in the universe. They are not most common type of star.
red dwarf is the most nearest star.
Red Dwarf Stars
There are billions of red dwarf stars. I will name just one and it's the nearest star (apart from the Sun). That red dwarf star is the famous "Proxima Centauri".
A red dwarf is just like what most main-sequence stars are made of, they are mainly made up of hydrogen and helium.
Red dwarf stars may be the most common stars throughout the galaxy, and possibly the universe. They are so dim, however, that they are difficult to see.The red dwarf Proxima Centauri is the closest star to our Sun; however, it is not visible without a telescope. Doubtless there are a great number of stars further away that are entirely lost to view because they are so dim.If two stars have approximately equal apparent magnitudes, the dim & tiny red dwarf star is far closer than the enormous red giant.
Most of the stars you can see are dwarf stars.Blue dwarf - Hypothetical star when a red dwarf exits the main sequence.White dwarf - Remnants of a Solar class star when it dies.Yellow dwarf - A star similar to our own SunOrange dwarf - A star just a bit smaller than our Sun.Red dwarf - A star which fuses hydrogen very slowly. The most abundant.Black dwarf - Hypothetical star when a white dwarf cools to zeroBrown dwarf - A "star" that did not have enough mass to fuse hydrogen.Examples:Blue dwarf - Unknown.White dwarf - 40 Eridani, IK Pegasi BYellow dwarf - The Sun, Alpha Centauri A,Orange dwarf - Alpha Centauri B, Epsilon Indi.Red dwarf - Proximus Centauri, Gliese 581Black dwarf - Unknown.Brown dwarf - 2M1207b, MOA-2007-BLG-192Lb.
Red dwarf star Wolf-Rayet star are two
Bernard's star and Mira are both red stars. Mira is a red giant star while Bernard's star is a red dwarf star.
Brown Dwarfs (maybe not true stars)Red Dwarfs (on the main sequence)Orange Dwarf (on the main sequence)Yellow Dwarfs (stars smaller than our sun but on the main sequence)White Dwarfs (old stars that have run out of hydrogen and are now off the main sequence)Neutron Stars (old large stars who's cores have collapsed during a supernova)---------------------------------------------------------------------------------Red dwarf - Like Proxima Centauri.White dwarf - A degenerate star. The remains of a Sun like star.Yellow dwarf - A G type main sequence star, like our own SunBlue dwarf - A hypothetical star formed from a red dwarf.Brown dwarf - A star that did not have enough mass to initiate nuclear fusion.Black dwarf - A hypothetical star formed when a white dwarf has cooled to absolute zero.Orange dwarf. A K type main sequence star, like Alpha Centauri B
Basically, none. Red dwarf stars have a lifetime that is much larger than the age of the Universe.Actually, if a lot of additional mass falls on a red dwarf star, it would start to burn more quickly. But then, of course, it would no longer be a red dwarf star.
