Where do the cool, faint, low-mass stars cluster on the Hertzsprung-Russell (H-R) diagram?

Answer

The lower-right corner

The Hertzsprung-Russell (H-R) diagram provides a graphical representation of stellar properties, correlating luminosity (or absolute magnitude) with surface temperature (or spectral type). On this diagram, the main sequence runs diagonally across the plot. The high-mass, hot, and luminous stars—those living brief, brilliant lives—are found situated in the upper-left section, reflecting their high energy output and temperature. Conversely, the cool, faint stars, which are inherently low-mass and extremely frugal with their fuel, occupy the opposite extreme. These long-lived, low-luminosity stars cluster together in the lower-right corner of the H-R diagram, signifying their potential for almost eternal stability during their main-sequence phase.
