摘要
From a survey of spectra of Bn/An stars; we have detected seven new Be stars: HR 1056 (A0Vn), 1544 (A1Vn), 2191 (A0Vnn), 2300 (B8Vn), 3134 (B9.5 Vn); 3878 (B0.5 IIIn) and 4552 (B9IIIpSi). H-alpha profiles of these stars are presented. Measured values of equivalent widths, full widths at half intensity maximum, and the peak-separations of the H-alpha emission profiles are also tabulated in this paper. We have also computed the radii of emission disks of the newly detected Be stars.
