    Ultraviolet and infrared monitoring of FG Sagittae during 1982-1989 - Evolutionary status
    Ultraviolet IUE spectra and infrared JHKL photometry of FG Sge obtained over the period 1982-1989 indicate that the cooling rate of the star observed until...

    Ultraviolet and optical spectroscopy of a B supergiant star in M 31
    We present and discuss the UV spectrum of the supergiant star in NGC206-277 in M 31, obtained with the Faint Object Spectrograph (FOS) on Hubble Space Telescope...

    Variability of NGC 5543: The continuum
    Simultaneous UV and optical variations of NGC 5548 suggest a common origin of the continuum flux at both ranges. If the bulk of the UV flux had a black body...

    Variability of NGC 5548: The lines
    Two broad components in the strongest UV emission lines of NGC 5548 are identified. The components respond differently to continuum changes. A normal broad...
