Spectrograms of HD 108 covering a wide spectral range (3200 Å-8000 Å) have been obtained in 1971 and 1972 at the Haute Provence Observatory. They are described in detail in the present paper and they are compared to previously published observations. New emission lines have been detected (3806 Å, 4415 Å, 4417 Å, 6340 Å) as well as new rapid intensity variations (He I: 4026.2 Å, 4387.9 Å; N III: 3s4P0-3p4D and 42F0-52G; Si IV: 4s2S-4p2P0). The measured radial velocities are compatible with an expanding atmosphere which exhibit a marked acceleration toward the outer layers. [less ▲]

Whereas HD 45677 has faded by approximately one magnitude since 1969, the amplitude of variation in photographic magnitude between 1899 and 1969 has always been smaller than 0.3 mag.

The iron atom which has a fairly high cosmic abundance presents the great interest of appearing in a wide variety of stars and nebulae, at many stages of ionization, and of revealing forbidden transitions in emission in many of these ionization stages. The present paper discusses the following topics : (a) the case of the as yet undiscovered forbidden lines of neutral iron (Fe0) ; (b) some recently acquired astronomical information on the forbidden lines of the stages Fe+ to Fe6+ ; (c) general considerations on the important information revealed by these forbidden lines of iron on the physical structure and excitation mechanisms which are present in the emission line stars of early and late types. For lack of time we give only a very summarized version of our paper ; a complete text will appear later. [less ▲]
