Abstract

We present the results of measurements of magnetic fields, radial velocities and rotation velocities for 92 objects, mainly main-sequence chemically peculiar stars. Observations were performed at the 6-m BTA telescope using Main Stellar Spectrograph with a Zeeman analyzer. In 2010, twelve new magnetic stars were discovered: HD\,17330, HD\,29762, HD\,49884, HD\,54824, HD\,89069, HD\,96003, HD\,113894, HD\,118054, HD\,135679, HD\,138633, HD\,138777, BD\,+53.1183. The presence of a field is suspected in HD\,16705, HD\,35379 and HD\,35881. Observations of standard stars without a magnetic field confirm the absence of systematic errors which can introduce distortions into the measurements of longitudinal field. The paper gives comments on the results of investigation of each star.
