The star is also called '''Purple Pleione'''. In the best-selling 1955 [[nature]] book published by [[Time-Life]] called ''The World We Live In'' , there is an artist's impression of Pleione in which it is called ''Purple Pleione''. The star is stated to be a rapidly rotating star and is shown in the illustration as being highly oblated and exhibiting a pale bluish-violet color with a ring of glowing [[red]] [[hydrogen]] gas around it. The part of the star that is seen through the gas appears a [[magenta]]-[[purple]] color in the illustration.

Purple Pleione

The star is also called Purple Pleione. In the best-selling 1955 nature book published by Time-Life called The World We Live In , there is an artist's impression of Pleione in which it is called Purple Pleione. The star is - incorrectly - stated to be a rapidly rotating star and is shown in the illustration as being highly oblated and exhibiting a pale bluish-violet color with a ring of glowing red hydrogen gas around it. The part of the star that is seen through the gas appears a magenta-purple color in the illustration.

The caption under the illustration (the original of which is a painting by the famed space artist Chesley Bonestell) states: "Purple Pleione, a star of the familiar Pleiades cluster, rotates so rapidly that it has flattened into a flying saucer and hurled forth a dark red ring of hydrogen. Where the excited gas crosses Pleione's equator, it obscures her violet light." [1]
