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 region 4100-8900Å of the
spectrum of MWC 297. About two hundred features are identified, almost
exclusively emission lines. Only one interstellar feature could be
identified (λ6613) a fact which contrasts with the eigth
magnitudes of extinction found by photometrists. The spectrum of the
underlying star corresponds probably to a late O or early B-type
object. The cooler emission lines correspond to a spectrum of a middle
A-type star. Analogies with other stars observed in this series of
papers are examined.
