Magnetic stars, 2004, 247-249 Study of magnetic fields of different luminosity hot stars Butkovskaya V., Plachinda S. Crimean Astrophysical Observatory, Nauchny, Crimea, 98409, Ukraine Abstract. Circular sp ectrop olarimetric observations of four different luminosity hot stars were obtained in an attempt to detect magnetic fields via longitudinal ° Zeeman effect in the sp ectral line HeI 6678.149 A: Pegasi (Sp B2 IV), Orionis (Sp B2 I I I), Orionis (Sp B3 I I Ie), Persei (Sp B1 Ib). ...
