On the Hertzsprung-Russell (H-R) diagram, where do red dwarfs typically occupy?
Answer
The lower right-hand section of the main sequence
The Hertzsprung-Russell (H-R) diagram is the primary tool used by astronomers to categorize stars based on their luminosity (vertical axis) versus their effective surface temperature or spectral type (horizontal axis). Stars spending most of their active lives fusing hydrogen reside on the main sequence. Red dwarfs are inherently cool and dim compared to stars like the Sun (a G-type star). Therefore, on the H-R diagram, they populate the lower end of the main sequence, situated towards the right side where temperatures are lowest and luminosities are minimal.
