Magnetic survey of bright northern main sequence stars.

MONIN D.N., FABRIKA S.N. and VALYAVIN G.G.

Abstract (from CDS):

The first results of a systematic search for magnetic fields in the brightest upper main sequence (MS) stars are presented. The main goal is to survey the stars with about the same detection limit and to improve existing statistics of their magnetism. The target list contains 57 upper MS stars and represents well B0.5-F9 stars. High-resolution Zeeman spectra were obtained for 30 stars of the list. The accuracy of the magnetic field measurements ranges from 20 to 300G depending mainly on spectral class. In the majority of studied stars we did not detect magnetic fields. In some stars we suspect the presence of a weak magnetic field. These are the best candidates for more extensive studies. A particular case is the star χDra where we probably detected the global magnetic field. The longitudinal field strength is B_l=-54±12G. Further observations of this star are needed to confirm the detection and to ascertain if the magnetic field is variable with the period of rotation.
