Peculiar stars in the Pleiades group.

Spectroscopic data for the 22 peculiar stars in the Pleiades group are analyzed. Estimates of the quantitative spectral class, type, and degree of peculiarity are obtained together with predictions of log g and the rotation rates. The estimates are based on high-resolution spectra obtained with the main stellar astrograph of the 6-meter telescope at the Special Astronomical Observatory in Nizhni Arkhyz, USSR. The average age of the stars was derived from the magnitudes in violet and the (U-B)O diagram. An age of 3 x 10 to the 7th yr was obtained. Estimates of the physical parameters of the stars are given in a table.
