RAPID OSCILLATIONS IN THE SPECTRUM OF roAp STARS χ PSC AND γ EQU

Results of high time and spectral resolution spectral observations with CCD in 1998-1999 for Ap stars χ Psc and γ Equ were presented. Spectroscopic parameters (Vr, Wλ) of spectral lines SiII, CrI, CrII, FeI, FeII, Hα, Hβ shows that despite of different value of rotation velocity of χ Psc (180 km/s)...
