The region of the Hertzsprung-Russell diagram with the most stars is the main sequence. This area, which stretches diagonally from the upper left (hot, luminous stars) to the lower right (cool, dim stars), contains about 90% of all stars, including our Sun. Main sequence stars primarily fuse hydrogen into helium in their cores, and this phase constitutes the longest stage in a star's life cycle.
The main sequence - the region across the middle of the diagram.
Most stars fall within the main sequence region of the Hertzsprung-Russell diagram. This area stretches diagonally from the upper left (hot, luminous stars) to the lower right (cool, dim stars) and accounts for about 90% of a star's life cycle, where they fuse hydrogen into helium in their cores. The main sequence includes a wide variety of stars, from massive O-type stars to smaller M-type stars.
Red dwarf stars are located in the lower right corner of the H-R diagram, which means they are cool and dim compared to other stars. They are low-mass stars that have a long lifespan and are the most common type of star in the universe.
The location on the Hertzsprung-Russell (H-R) diagram where most stars lie is known as the main sequence. This diagonal band extends from the upper left (hot, luminous stars) to the lower right (cool, dim stars) of the diagram. Main sequence stars, including our Sun, primarily fuse hydrogen into helium in their cores, which is the dominant phase of stellar evolution for the majority of stars.
The "main sequence" is the region (on the HR diagram) for stars which burn hydrogen-1. Once stars use up most of their hydrogen-1 (and have significant amounts of helium-4), they leave the main sequence.

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.

Red dwarf stars are located in the lower right corner of the H-R diagram, which means they are cool and dim compared to other stars. They are low-mass stars that have a long lifespan and are the most common type of star in the universe.
Most stars lie along the main sequence of the Hertzsprung-Russell (HR) diagram, which runs diagonally from the top left (hot, luminous stars) to the bottom right (cool, dim stars). This region accounts for about 90% of all stars, including our Sun, as they spend the majority of their lifetimes fusing hydrogen into helium in their cores. The main sequence is characterized by a balance between gravitational collapse and the outward pressure from nuclear fusion.

In the HR-diagram, a diagram of color vs. luminosity, most stars are concentrated close to one curve, called the "main sequence". It turns out that stars on the main sequence are the stars that mainly get their energy by converting hydrogen into helium.
The curve that currently contains most stars on the HR diagram is called the "main sequence". It consists of those stars that fuse hydrogen-1, converting it into helium-4.
