Ultrafast Variability of Line Profiles in Spectra of γ Ori

Ultrafast Variability of Line Profiles in Spectra of γ Ori High time-resolution (∆T~2 min) observations of the B2V star γ Ori on the 2-m telescope at the Terskol Peak Observatory are presented. Regular components of line profile variations with periods from ~57 min to ~130 min are recorded. The nature of these variations is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Astrophysics Springer Journals

Abstract

High time-resolution (∆T~2 min) observations of the B2V star γ Ori on the 2-m telescope at the Terskol Peak Observatory are presented. Regular components of line profile variations with periods from ~57 min to ~130 min are recorded. The nature of these variations is discussed.
