Results of Magnetic-Field Measurements with the 6-m Telescope. V. Observations in 2011

详细

The paper presents results of measurements of magnetic-field longitudinal components B_e, radial velocities V_r, and projections of the rotation velocity in the line of sight v_e sin i for 74 objects, mainly main-sequence chemically peculiar stars and standard stars. Observations were carried out in 2011 at the 6-m BTA telescope using the Main Stellar Spectrograph (MSS) with a Zeeman analyzer. Seven new magnetic stars were discovered: HD38129, HD47152, HD50341, HD63347, HD188501, HD191287, and HD260858. Three more stars were suspected to have magnetic fields. Observations of magnetic standard stars and non-magnetic stars confirm the absence of any systematic errors capable of introducing distortions into the B_e longitudinal-field measurement results. The paper gives comments on the research results for each of the 74 stars.
