White dwarf stars (circled) in globular cluster M4.The brightest stars in this field are yellow stars similar to the Sun; smaller, dim stars are red dwarfs.

Hertzsprung-Russell diagram of solar neighbourhood

A Hertzsprung-Russell diagram plotting stars by absolute magnitude and spectral type, showing regions for main sequence stars, white dwarfs, giants, and supergiants, with color gradients from blue (hot and bright) to red (cool and dim). The Sun is marked along the main sequence.

Diagram illustrating stellar evolution, showing how stars form from a nebula, then follow different paths based on mass: low- and medium-mass stars become red giants, then planetary nebulae, and end as white dwarfs; high-mass stars become red supergiants, explode as supernovae, and end as either neutron stars or black holes.
