Pecular stars in the Pleiades group

For 22 peculiar stars from the Pleiades Group, the quantitative spectral types, the type and degree of peculiarity of the spectra, the effective temperatures Tsub(e), the surface gravity lg g, and the velocities of rotation v sin i are determined using the high-resolution spectrogrammes (WElambda=0.25 A), obtained with the Main stellar spectrograph of the 6-meter telescope. The age of the stars of the group t=3x107 years is estimated from the [Msub(V), (U-B)0] diagramm
