Cool and luminous stars would be located in the top right corner of a Hertzsprung-Russell diagram, in the region known as the red giant branch.

Pollux is an orange giant star located about 34 light years from earth. It would no doubt have been used to help form the Hertzsprung-Russell diagram, showing temperatures of stars vs. luminosity. Its temperature is around 4865 Kelvin and it has a luminosity of 32 times that of our own sun.
Stars in their giant and supergiant stages are located in the top right portion of the Hertzsprung-Russell diagram, also known as the "red giant branch." These stars are characterized by being large and cool compared to main sequence stars, and they represent later stages in stellar evolution.
Neutron stars are significant on the Hertzsprung-Russell diagram because they represent the final stage of stellar evolution for massive stars. They are located in the lower left corner of the diagram, known as the "degenerate dwarf" region, due to their small size and high density. Neutron stars help scientists understand the life cycle of stars and the different stages they go through.
A star that is burning hydrogen into helium in its core is typically located on the main sequence of the Hertzsprung-Russell diagram. The position on the main sequence depends on the star's mass and temperature; more massive stars are found toward the upper left, while less massive stars are located toward the lower right. Main sequence stars are characterized by their stable hydrogen fusion, which defines their luminosity and temperature.
The least massive main sequence stars on the Hertzsprung-Russell (H-R) diagram are red dwarfs, which are classified as spectral types M. These stars have masses typically less than 0.6 solar masses and are located on the lower right portion of the H-R diagram. Red dwarfs are characterized by their low luminosity and temperature, and they are the most common type of star in the universe.
The least massive main-sequence stars on the Hertzsprung-Russell (H-R) diagram are the red dwarfs, which are located in the lower right section of the diagram. These stars have masses less than about 0.6 solar masses and are characterized by their low temperatures and dim luminosities. Red dwarfs are the most common type of star in the universe and can burn for billions of years due to their efficient fusion processes.
The sun is located on the main sequence of the Hertzsprung-Russell diagram, specifically in the middle region known as the "G-type" or "yellow dwarf" star category. This is where stars like the sun primarily reside during their hydrogen-burning phase.
The main sequence stars located at the bottom right of the Hertzsprung-Russell diagram are the least massive. These stars are low in temperature and luminosity, such as red dwarf stars, which have masses less than about 0.4 times that of the Sun.
The brightest star on the Hertzsprung-Russell diagram is typically found in the upper left corner, representing massive, hot, and luminous stars known as supergiants or giants. These stars have high luminosities and are located in the top portion of the diagram.
