Short-periodic light variations in Wolf-Rayet stars.
Abstract
Three Wolf-Rayet stars were investigated for short-periodic light variations by means of narrow band photometry. Both emission lines and the continuum were observed. No stable variation in the period range 1-10 min was found. The only star observed on several nights, gamma 2 Vel, showed definite variations in the emission line strength from night to night.
