late-type star





A star of spectral type K, M, S, or C, with a surface temperature lower than that of the Sun. The term dates from when astronomers thought that all cooler, redder stars like these were at a later stage of evolution than the hot blue, white, and yellow-white stars of spectral types O, B, A, and F which were said to be called early type.
