On a Hertzsprung-Russell diagram, where would we find stars that are cool and dim?

Question

BlackTom AI · Accepted Answer

On a Hertzsprung-Russell diagram, stellar properties are represented with temperature along the horizontal axis (usually decreasing to the right) and luminosity along the vertical axis. 
First, consider what 'cool' and 'dim' mean in this diagram: cool stars have lower surface temperatures and appear redder, while dim stars have lower luminosities. 
In the standard HR diagram layout, cool stars lie toward the right side, and dimmer stars lie toward the bottom. 
Therefore, stars that are both cool and dim would be located toward the lower-right region of the diagram. 
To contrast, hot and bright stars would appear in the upper-left, hot and dim would be lower-left, and cool and bright would be upper-right, which helps reinforce why the lower-right position corresponds to cool, dim stars. 
Given the prompt and the provided answer, 'lower right' correctly identifies the region for cool, dim stars on an HR diagram.
