Ae and A type shell stars

We present and discuss the observations of 14 Ae and A type shell stars in the visual, the Hα region and the near infrared. At least 57% of these stars are spectrum variables. The Paschen lines are formed in a region which has the characterics of giant stars. We find that the systems lie one magnitude above the main sequence and that a large percentage belong to double and triple...

B[e] stars. I. HD 51585 (=OY Gem)

We analyse CCD spectroscopic material obtained at the Haute Provence Observatory between 1990 and 1993, covering the wavelength region 3800-11000 Å. 320 emission lines were measured and identified. Of these about 40% correspond to permitted or forbidden lines of ionized iron. Many forbidden lines (20% of the total) are present, including many classic nebular lines. We also...

B[e] stars. II. MWC 349 A

We analyse spectroscopic CCD material obtained at the Haute Provence Observatory. We provide line identifications and equivalent width measurements in the wavelength region 3700-8790 Å. Over 300 emission features are identified and a comparison of our results with those of other authors is provided, as well as a table of all elements which have been identified in the spectrum of...

Higher Paschen lines in the spectra of early-type stars

We present observed and computed line profiles of Paschen lines in two nearly atmospheric absorption-free spectral regions: 8350 to 8790 Å and around the P7 line. We show that the Edmonds, Schlüter & Wells semi-empirical theory of line broadening is suitable for the computation of higher members of the Paschen series. We compare the variations of the equivalent widths of P7 and...

New near-infrared CCD spectra of two infrared-excess B[e] stars ⋆

We report in this paper recent observations, mainly in the region from 0.7 to 1.03 μm, of two peculiar emission-line objects, HD 50138 and 45677, and discuss the similarities and dissimilarities in their spectra.
