Description

With this work we provide observational material to study magnetic field variability of the classical beta Cep-type star gamma Peg. The observations were carried out in the HeI 6678 line in the course of 23 observing nights from 1997 to 2005 with using coude spectrograph in spectropolarimetric mode at the Crimean 2.6m telescope. The behavior of stellar wind was studied in the UV region using data from the IUE satellite (the INES database). It is shown that the UV stellar wind exhibits a variability. A variation of the wind due to stellar pulsations has been detected. In the HeI 6678 line the abnormally blueshifted radial velocities (gamma=-60.57+/-0.29km/s) were detected during a single night in 2005. We do not confirm the 370.5-day orbital period. The most probable orbital period was estimated as P_orb_=6.81608+/-0.00012d. The ratio P_orb_/P_puls_=44.92 appeared to be very close to integer. We have detected the presence of weak magnetic field on the star. The longitudinal component of the field varies from -10G to 30G with the stellar rotation. The most probable rotational period is P_rot_=6.6538+/-0.0016d. Both the orbital and the rotational periods are integral multiple of the difference between them: P_orb_/|P_orb_-P_rot_|=42.002, and P_rot_/|P_orb_-P_rot_|=41.002. Variation of the longitudinal magnetic field during pulsation period with an amplitude about 7G has been detected.
