A Spectrographic Study of the Shell Star EW Lac
Published online by Cambridge University Press: 14 August 2015
Abstract
38 Zeeman spectrograms of the Be star EW Lac (HD 217050) were obtained in three successive years, 1978, 1979 and 1980. The investigated lines show long-time variations of the radial velocities, line widths, and line intensities. No hints at the occurrence of a global magnetic field larger than 150 Gauss were found.
