Search for Ultrafast Variability of Line Profiles in the Spectrum of ε Per A

The results of observations at high temporal resolution (∆T~4 min) of the B0.5V star ε Per A on the 2-m telescope of the Terskol Observatory are reported. Regular components of variations in line profiles with periods 1.5-18 hours are recorded. Evidence of irregular variations in line profiles on ti...

Zusammenfassung:The results of observations at high temporal resolution (∆T~4 min) of the B0.5V star ε Per A on the 2-m telescope of the Terskol Observatory are reported. Regular components of variations in line profiles with periods 1.5-18 hours are recorded. Evidence of irregular variations in line profiles on time scales of minutes is detected. The nature of these variations is discussed.
