| Abstract: |
A regular monitoring of the longitudinal magnetic field variability (Be) of the long-period
Ap star GY And (HD 9996, P = 7962 days) has been carried out with the SAO RAS 1-m telescope.
The monitoring showed that at the phases of the maximum and minimum strength of the longitudinal
magnetic field there possibly exists additional unharmonic variability of
the longitudinal magnetic field giving rise to a scatter of individual magnetic
field measurements. This additional component of Be variability requires
further long-timescale monitoring
for its confirmation and the clarification of its nature.
We also present, for the first time, long-term series of UBV
photometric observations of this star during a length of time
approaching 10 years. |
