The stellar wind and the UV spectrum of (nova) HR Delphini.
Hutchings, J. B.
Low-resolution ultraviolet spectra of HE Del have been obtained with the IUE satellite. The continuum matches a high g stellar atmosphere with Teff ∼ 15,000 K, EB-V ∼ 0.2. However, the line spectrum contains resonance features of high ionization, with P Cygni profiles indicating outflow at more than 2300 km s-1 fro…
The ultraviolet spectrum of LSI +61 303.
Hutchings, J. B.
IUE spectroscopy is presented of the radio variable emission-line star LSI +61°303, which may also be a source of X and γ rays. The UV continuum is complex and dues nut fit a single stellar model or power law. The UV flux and line spectrum suggest the primary is a mass-losing Ib supergiant but all possibilities involve some peculiarities compared …
IUE spectra of the massive close binary V382 Cygni.
Koch, R. H.; Siah, M. J.; Fanelli, M. N.
The massive close binary, V382 Cyg, was observed with the low-dispersion spectrograph on the IUE satellite. The dereddened spectrum can be reasonably represented by a 40,000-K model atmosphere. The spectra show interstellar, photospheric, and shell absorption blends and one shell emission feature. From one of the shell absorptions, it is possible …
