Angela John Thurman,Laura del Hoyo SorianoRecent GHRS observations of the Herbig Ae star AB Aur demonstrate the presence of N V in the wind of this star. We found that models including hot (T≈140,000 K) clumps are able to reproduce the available observations and are also consistent with its X-ray emission.

High-Resolution Spectroscopy of HD 45677We present high-resolution spectra of the peculiar B star HD 45677 (FS CMa) obtained at 3 observing nights. In our paper we focus on the variability of Balmer and neutral helium lines.

The Galactic B Supergiant Candidate HD 87643HD 87643 has long been known as a peculiar B-type emission line star. Its spectrum is dominated by emission lines from FeII and the Balmer series. Of particular note is the P Cygni shape of the hydrogen and helium lines. Except for the blue-shifted absorption components and interstellar absorption lines, no absorption lines have been found.

The parallaxes of Be stars were only determined by indirect methods. However, because their absolute magnitude is a clue for the understanding of the Be phenomenon which is up t
