    A spectral classification system for hydrogen-deficient carbon stars
    Stellar spectral classification has been highly useful in the study of stars. While there is a currently accepted spectral classification system for carbon...

    A spectral diagnostic for density-bounded HII regions
    The existence of density-bounded HII regions in spiral galaxies is supported by means of a spectral indicator based on the intensity of the [OI]λ6300 forbidden...

    A spectrograph for exoplanet observations calibrated at the centimetre-per-second level
    The best spectrographs are limited in stability by their calibration light source. Laser frequency combs are the ideal calibrators for astronomical...

    A spectroscopic analysis of the Luminous Blue Variable candidate WRA 751
    We present spectroscopic observations of the LBV candidate WRA 751 taken at different epochs during the period 1989-1995. These observations are used to monitor...

    A spectroscopic analysis of the most polarizing atomic lines of the second solar spectrum
    We present an analysis of the second solar spectrum, as plotted in graphical form in the three volumes of the atlas “The Second Solar Spectrum”, in the...

    A spectroscopic and kinematic survey of fast hot subdwarfs
    Hot subdwarfs (sdO/B) are the stripped helium cores of red giants formed via binary interactions. Close hot subdwarf binaries with massive white dwarf...
