Two new bright Ae stars

/ Abstract
. Two newly identified Ae stars, ν Cyg and κ UMa, were discovered in the course of the Magnetic Survey of Bright MS stars (Monin et al. 2002). We present their H α profiles along with measurements of their equivalent width and parameters of emission features. Emission in the H α line of ν Cyg is variable on a time scale of 3 years. κ UMa exhibits weak emission which is rather stable. The emission is thought to arise from a circumstellar disk, and we have estimated the size of that disk.Both new emission stars are IRAS sources. Their IR color excesses are consistent with those of classical Ae stars. Thus, ν Cyg and κ UMa appear not to belong to the class of Herbig Ae/Be stars. We argue that the frequency of Ae stars may be underestimated due to the difficulty of detection of weak emission in some A stars.
