If a star has oxygen, then it is classified as an M-star. The chemistry of M-stars is relatively simple with water as the most important source of molecular opacity. However, transition metal oxides, particularly TiO, are also found to have prominent spectra.
In a newly formed star cluster, low-mass stars like red dwarfs are the most common. These stars are more abundant than more massive stars like giants or supergiants. The cluster will typically have a range of stellar masses, but low-mass stars dominate in numbers.
M-type stars, also known as red dwarfs, are the most common type of star and have the longest lifespans, estimated to live for trillions of years. Some M-type stars that are still around today are thought to have formed within the first few hundred million years after the Big Bang, making them some of the oldest stars in the universe.
Main Sequence
M Class stars have the following characteristics.Temperature: < 3,700 KelvinColour: Red -> Orange-redMass: < 0.45 Solar massesRadius: < 0.7 Solar radiusLuminosity: < 0.08 Solar luminosities.Rarity: 76.45% of all main sequence stars.Examples: BetelgeuseSee related link for more information.
from my text book: "The most luminous stars are so rare you find few in your survey region. There are no O stars at all within 62 PC of Earth. Lower-main-sequence M stars, called red dwarfs, and white dwarfs are so faint they are hard to locate even when they are only a few parsecs from earth."
The most common spectral type of stars in the universe is M, which includes red dwarfs and red giants. These stars are relatively cool and dim compared to other spectral types like O, B, or A.
The most common star category is the main sequence stars, which include stars like our Sun. Main sequence stars are in a stable phase of hydrogen fusion in their cores, which is why they are abundant in the universe.

The stars with an A-type spectrum are the hottest common stars, but early-stage stars with a B-type spectrum are even hotter. The order of temperature is B-A-F-G-K-M for common stars. The M-type stars are the coolest common stars and they definitely look red, e.g. Antares, Betelgeuse. Remember the order by learning this: Be A Fine Girl, Kiss Me!
Brown is the most common color.
Orange
Um, they are all made in a factory. pretty much all even. You fail.

According to m&m's official website it is blue. There are 22% blue in an average packet.
M stars contan metal oxides molecules.
