Scientific paper

Ultraviolet spectrograms of BD + 10 deg 2179 and BD - 9 deg 4395 were obtained with the International Ultraviolet Explorer in the low resolution mode. No evidence for mass loss was found. The observations were analyzed by comparison with detailed LTE-model fluxes including 800 atomic transitions. The results confirm earlier analyses of visual spectra.
