Abstract:
On the basis of spectroscopic CCD material obtained at the Haute
Provence Observatory, we provide line identifications and equivalent
width measurements in the wavelength regions 3750-5112 and
7065-10212{AA} of the spectrum of HD 45677. Over 235 features are
identified 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 7000K 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.

Note (1): a = absorption characteristic of the line
e = emission characteristic of the line
ed = double emission
* indicates that these lines come from a spectrum taken in 1990,
whereas the rest of the Paschen series comes from a spectrum
taken in 1993
Please notice that the regions 7000-7412 and 9025-9400 are very perturbed
by atmospheric absorption.
Wavelengths of unidentified lines are rounded off to the nearest tenth of
Angstroem.
Note (2): +p : refers to the preceding line
