B[e] stars IV. HD 45677 = MWC 142?

Abstract. On the basis of spectroscopic CCD material obtained at the Haute Provence Observatory, we provide line identications and equivalent width measurements in the wavelength regions 3750 − 5112 and 7065 − 10212 A of the spectrum of HD 45677. Over 235 features are iden-ti ed and a comparison of our results with those of other authors is provided. We also discuss the variability of the lines using equivalent widths and the line spectrum. We conclude that the gaseous shell surrounding the star has a temperature of the order of 7000 K and that its distance to the star is less than ten stellar radii. We discuss the similarity of this star to other stars previously analyzed. Key words: stars: emission line, B[e] | stars variables
