- Аннотация: AbstractBased on our measurements and data available from literature sources we performed periodogram analysis of the new dataset (459 observations) of the longitudinal components of the magnetic field hBzi of Ap star γ Equ. Conclusion about the existence of period P = 101.3 4.7 years (36962 days) was made. While approximation of the entire dataset using two sinusoids, the periods equal to 101.9 years and 16.7 years were established (with a margin of error of 4.7 years and 2.2 years, accordingly). New estimates of hBzimax = 577 Hz and hBzimin = 1101 Hz are obtained. The supposed date of transition to positive values of hBzi should not be earlier than 2031.
