Notes
17 Tau. This is classified as a Be star, which is a B-type star with prominent emission lines of hydrogen in its spectrum.[3] The Be stars have a rotation rate that is 1.5–2 times the rotation of normal B-type stars. This high rate of rotation may allow mass loss during even minor prominences.[8] Changes in the radial velocity measurements indicate that this star may have a companion, which would make Electra a spectroscopic binary.[14][15] However, follow-up studies including interferometry have failed to confirm any companion star(s), so it is likely a single star.[16]
