	H-R diagram - Wikipedia
		Actually, there are very metal-poor stars (subdwarfs[?]) that lie just below the main sequence although they are fusing hydrogen, thus marking the lower edge of the main sequence's fuzzyness due to chemical compositon.
		Stars usually enter and leave the main sequence from above when they are born or they are starting to die, respectively.
		In the lower-left is where white dwarfs are found, and above the main sequence are the red giants and supergiants.

	main sequence
		A star on the main sequence is one that is generating light and heat by the conversion of hydrogen to helium by nuclear fusion in its core.
		A star's position and length of stay on the main sequence depend critically on mass.
		The least massive, hydrogen-burning stars, the red dwarfs, sit to the lower right and may remain on the main sequence for hundreds of billions of years.

		Image:H-R diagram.png The main sequence of the Hertzsprung-Russell diagram is the curve where the majority of stars are located in this diagram.
		Another common method of calculating main sequence lifetime is to take the result of the above calculation and multiplying the answer by the Sun's main sequence lifetime of 10 billion years.
		Main sequence is also the name of a composition of music by composer Vangelis on his 1976 album, Albedo 0.39 and is in reference to the astronomical term.

	Main Sequence, Mu-Ency at MROB
		The Main Sequence is the set of secondary continental mu-atoms with internal angle 1/N for integer N>2, and R2 names R2.1/Na; the first few are R2.1/2a, R2.1/3a, R2.1/4a, etc. See also the entries for R2 and R2C(0).
		The orbital dynamics of the main sequence mu-atom R2.1/Na is the simplest of all period-N mu-atoms.
		The main sequence mu-atoms decrease in size in a manner that is proportional to the cube of the period: the main-sequence mu-atom of period 2N will be 1/8 the size of the main-sequence mu-atom of period N.

	Hertzsprung-Russell diagram
		The stars in the lower right corner of the main sequence are frequently called red dwarfs, and the stars between the main sequence and the giant branch are called subgiants.
		The significance of the H-R diagram is that stars are concentrated in certain distinct regions instead of being distributed at random.
		Thus, the point at which the main sequence terminates and the giant branch begins is an indication of the age of a star cluster.

		Evolutionary state of stars prior to arrival on the main sequence, especially just before the main sequence is reached.
		Large organic molecule composed of one or more chains of amino acids, as determined by the base sequence of nucleotides in the gene coding for the protein.
		Proteins are required for the structure, function, and regulation of the cells, tissues, and organs of carbon-based life.
