Pleione

(plee -ŏ-nee, plÿ -) (28 Tau) One of the stars of the Pleiades. It developed a surrounding envelope that was first observed in 1938, reached maximum intensity in 1945, and was just visible in 1954; another shell started to develop in 1972. It is thought to be unstable owing to its fast rotation rate. Spectral type: B8pe.
