赤色超巨星
1. Red supergiantRed supergiants (RSGs) are supergiant stars of spectral type K or M. They are the largest stars in the universe in terms of volume, although they are not the most massive. Betelgeuse and Antares are the best known examples of a red supergiant. After the hydrogen in a star's core has fused, stars with more than about 10 solar masses become red supergiants for the duration of their helium-fusing phase. These stars have very cool surface temperatures (3500–4500 K), and enormous radii.
