Explanation:
Detailed explanation-1: -The group called the main sequence extends in a rough diagonal from the upper left of the diagram (hot, bright stars) to the lower right (dim and cool). Large, bright, though cool, stars called giants and supergiants appear in the upper right, and the white dwarfs, dim, small, and hot, lie in the lower left.
Detailed explanation-2: -Most stars are main sequence, but most main sequence stars appear in the lower right corner of the HR diagram.
Detailed explanation-3: -Red dwarf stars are the most common kind of stars in the Universe. These are main-sequence stars but they have such low mass that they’re much cooler than stars like our Sun. This cooler state makes them appear faint.
