White dwarfs, red giants, and blue stragglers are all types of what?
Blue dwarf (red-dwarf stage) equilibrium. Stars larger than red dwarfs do this by increasing their size and becoming red giants with larger surface areas. Rather than expanding, however, red dwarfs with less than 0.25 solar masses are predicted to increase their radiative rate by increasing their surface temperatures and becoming "bluer". This is because the surface layers of red dwarfs do not become significantly more opaque with increasing temperature. Blue dwarfs eventually evolve into white dwarfs once their hydrogen fuel is completely exhausted, which in turn will eventually cool to become black dwarfs.

Cow's Skull: Red, White, and Blue Cow's Skull: Red, White, and Blue Cow's Skull: Red, White, and Blue is a painting by American artist Georgia O'Keeffe. The painting depicts a cow skull centered in front of what appears to be a cloth background. In the center of the background is a vertical black stripe. On either side of that are two vertical stripes of white laced with blue. At the outside of the painting are two vertical red stripes. O'Keeffe created the painting in 1931. It is done in oil on canvas and measures 39 7/8 x 35 7/8 inches. (101.3 x 91.1 cm). It is
