Evolutionary Features and Other Characteristics of Magnetic Stars with Helium Anomalies (He-r, He-w)
Abstract
—We critically review the results of earlier studies on magnetic stars with anomalous helium lines. We discuss the issues associated with the fossil-field theory and the scenario of the formation of magnetic stars. A special feature of the results of our study is that they are derived from more than 160 direct estimates of average surface magnetic fields Bs or models obtained by the method. The difficulty of this work is in the insufficient amount of data on He-r stars. The problem is caused by a great decrease of the v sini values of stars at the time of internal restructuring.
