main sequence
In an H-R diagram, summer (or main sequence) stars are located along a diagonal band from the upper left (hot and bright) to the lower right (cooler and dimmer). They are grouped around the center of the diagram, with the most massive stars located at the top left and the least massive stars at the bottom right.
The chart used to classify stars is called the Hertzsprung-Russell diagram (H-R diagram). This diagram plots stars based on their luminosity and temperature, helping to illustrate their evolutionary stages. It reveals relationships between different types of stars, including main-sequence stars, giants, and white dwarfs.
Hot stars are found in the left hand side of the diagram, cool stars the right, bright stars at the top, and lastly the faint stars are located at the bottom.
The location on the Hertzsprung-Russell (HR) diagram where most stars lie is known as the main sequence. The HR diagram is a plot of stellar luminosity against surface temperature. The main sequence is a prominent band that extends diagonally across the HR diagram from high temperature and high luminosity to low temperature and low luminosity. The majority of stars, approximately 90% of all stars, are situated along the main sequence on the HR diagram. These stars are often referred to as main-sequence stars. They exhibit a smooth relationship between surface temperature and luminosity, with varying sizes and masses but sharing this common characteristic of lying on the diagonal band from the upper left to the lower right of the HR diagram.

Main sequence stars on the Hertzsprung-Russell (HR) diagram represent stars going through stable nuclear fusion, converting hydrogen into helium in their cores. They occupy a diagonal band from hot, massive stars at the top left to cool, low-mass stars at the bottom right. This phase is the longest-lived stage in a star's life cycle.
Main sequence stars.
The great majority of stars are plotted along a diagonal band called the main sequence on an H-R diagram. This band represents stars that are fusing hydrogen into helium in their cores, where the varying luminosities and temperatures of stars are displayed.

They are grouped around the center of the diagram, with the most massive stars located at the top left and the least massive stars at the bottom right.
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.

An specific pattern of stars could be called a constellation.
Hot stars are found in the left hand side of the diagram, cool stars the right, bright stars at the top, and lastly the faint stars are located at the bottom.
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.
