New spectra have been obtained for the pole-on Be star HR 5223 (HD 120991) using the Far Ultraviolet Satellite Explorer (FUSE). We give a complete description of the far-UV spectral range (920 to 1180{AA}). The spectra are affected by strong blends with interstellar lines and molecular bands that also significantly lower the energy distribution of the star. We produce a synthetic spectrum of the interstellar medium (ISM) to determine the column densities of several elements (H_2_, H I, N I, O I ...) seen towards HR 5223 and to disentangle the components due to the ISM, the photosphere and/or to the circumstellar envelope.
Funded by NASA as part of its Origins program, FUSE was developed in collaboration with the space agencies of Canada and France, and is being operated for NASA by the Johns Hopkins University. FUSE was launched into orbit aboard a Delta II rocket on June 24, 1999 for at least three years of operations. FUSE (Far Ultraviolet Spectroscopic Explorer) provides spectra in the far ultraviolet portion of the electromagnetic spectrum (range 905-1180 Angstroems, or 90.5-118nm) with a high resolution of about 20000 (one point each 5pm).
