Magnetic Field Observations of the Ap Star γ Equ

Further investigations of the Ap star γ Equ (SCHOLZ , 1975) showed that a very slow variation of the longitudinal magnetic field exists, with a change of sign in the years 1970/1971. In three spectrograms obtained near of the crossover points of the longitudinal magnetic field hints are given at the presence of a transversal magnetic field of about 3500 Gauß. The radial velocity measurements show no definitive variations.
