    Evidence for binarity in the bipolar planetary nebulae A 79, He 2-428 and M 1-91
    We present low and high resolution long-slit spectra of three bipolar planetary nebulae (PNe) with bright central cores: A 79, He 2-428 and M 1-91. He 2-428 and...

    Excitation of emission lines by fluorescence and recombination in IC 418
    We compare calculated intensities of lines of C II, N I, N II, O I and O II with a published deep spectroscopic survey of IC 418. Our calculations use a self...
