The brightest stars of the cluster are named the Seven Sisters in early Greek mythology: Sterope, Merope, Electra, Maia, Taygeta, Celaeno, and Alcyone. Later, they were assigned parents, Pleione and Atlas. [18] As daughters of Atlas, the Hyades were sisters of the Pleiades. The following table gives details of the brightest stars in the cluster:
Alcyone / æ l ˈ s aɪ ə n iː /, [11] designated η Tauri (Eta Tauri, abbreviated Eta Tau, η Tau), is a star in the constellation of Taurus. Approximately 440 light-years from the Sun, it is the brightest star in the Pleiades open cluster, which is a young cluster, around 100 million years old. There are a number of fainter stars very close ...
Maia / ˈ m eɪ ə /, designated 20 Tauri (abbreviated 20 Tau), is a star in the constellation of Taurus. It is a blue giant of spectral type B8 III, a chemically peculiar star, and the prototype of the Maia variable class of variable star. Maia is the fourth-brightest star in the Pleiades open star cluster (Messier 45), after Alcyone, Atlas ...
In 1942 Otto Struve, one of the early researchers of Be Stars, stated that Pleione is "the most interesting member of the Pleiades cluster". [20] Like many of the stars in the cluster, Pleione is a blue-white B-type main sequence dwarf star with a temperature of about 11,000 K. It has a bolometric luminosity of 184 L ☉ assuming a distance of ...
Electra / ə ˈ l ɛ k t r ə /, [11] designated 17 Tauri, is a blue-white giant star in the constellation of Taurus located approximately 400 light years away. It is the third-brightest star in the Pleiades open star cluster (), visible to the naked eye with an apparent magnitude of 3.7.
Taygete was one of the Pleiades sisters in Greek mythology. In 2016, the IAU organized a Working Group on Star Names (WGSN) [10] to catalogue and standardize proper names for stars. The WGSN approved the name Taygeta for the component 19 Tauri Aa on 21 August 2016 and it is now so included in the List of IAU-approved Star Names. [7]
The first list shows a few of the known stars with an estimated luminosity of 1 million L ☉ or greater, including the stars in open cluster, OB association and H II region. The majority of stars thought to be more than 1 million L ☉ are shown, but the list is incomplete. The second list gives some notable stars for the purpose of comparison.
