On the HR diagram each star occupies a single point, depending on its surface temperature (horizontal) and its absolute magnitude (vertical).
The "supergiant" stars are the brightest stars on the H-R diagram.
Stars are classified by the H-R scale. They are classified by their luminosity and their temperature. They can also be classified by stage; our sun is a main sequence star while the center of the milky way is a black hole(the corpse of a super massive star).
Several regions of the HR diagram have been given names, although stars can occupy any portion. The brightest stars are called supergiants. Star clusters are rich in stars just off the main sequence called red giants. Main sequence stars are called dwarfs.
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.

A star is a large, naturally occurring fusion reactor. Stars are classified by size, content, heat, and position within life cycle.
The most massive type of main sequence star on the HR diagram would be indicated by the main sequence area at the top left of the HR diagram, which would be blue or violet in color. Zeta Puppis is an example of such a star. It comes in at 40 solar masses. It is classified as a type "O" star.
Based on initial size and chemical composition a star will enter a band on the HR diagram as a mains sequence star. Stars on the main sequence are in equilibrium from thermal pressure trying to enlarge the star and gravitational pressure trying to collapse the star. Stars on the main sequence range from massive hot blue-white stars to much less massive red stars.

Stars are classified by their type and temperature. Amongst some of the types of stars in our galaxy are white dwarfs, blue giants, and red supergiants. Our own Sun is a yellow dwarf, and like most stars is a main-sequence star.
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.
The most massive main sequence stars are the brightest, (O main sequence star on Hertzsprung-Russel Diagram). Main sequence stars obey a mass-luminosity relation. On the H-R diagram the vertical axis is the brightness. So the stars along the top are the brightest (intrinsically).
The Sun is classified as a medium to medium-small yellow star. As stars in our galaxy go, the Sun is, truthfully, about as ordinary as stars get - but it does the job!
