Results of magnetic field measurements of CP stars carried out with the Russian 6-m telescope. I. Observations in 2007

Abstract

This paper presents the results of magnetic field measurements for 39 chemically peculiar and 3 normal main sequence stars used as standard stars. Observations were carried out with the Main Stellar Spectrograph of the Russian 6-m telescope during 2007. Zeeman measurements for 8 stars were performed for the first time. The accuracy analysis for the longitudinal magnetic field measurements of the stars confirms that the systematic errors do not exceed 10–20 G and are within the quoted limits. The absence of significant instrumental deviations follows from the measurements of the CP stars with well-known B e variation curves.
