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.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
