Abstract
Effects of temperature and pressure changes during pulsation cycle on line profiles in beta Cephei stars are investigated. We find significa nt changes in residual intensities, FWHM and equivalent widths for rad ial pulsations when both these effects are included in model calculati ons. Radial velocity curves are also discussed. The presented approach may be useful for simultaneous analysis of continuum and line profile s variations in pulsating stars.
