The main sequence stars are those that extends in a rough diagonal moving upper left of the diagram HR diagram to the lower right, which is when you move from the stars that are bright to dim ones they can be found the between temperature of 40,000 and 2,500 degrees Celsius.
<h3>What is Hertzsprung-Russell diagram?</h3>
The Hertzsprung-Russel Diagram serves as a stars' scatter plot that do show the the relation of luminosity as well as the surface temperature of the stars.
In this diagram the intrinsic brightness of stars and the their spectral types are been plotted against each other.
Check the attachment for a HR diagram.
