    Early results from ChanPLaNS: Mystery of hard X-ray emitting CSPNe†
    We are presently using the Chandra X-ray Observatory to conduct the first systematic X-ray survey of planetary nebulae (PNe) in the solar neighborhood. The...

    Energy implications of temperature fluctuations
    We quantify the energy radiated through all the collisional lines in a photoionized nebula in the presence of temperature fluctuations in the form of hot spots...

    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...

    Evolutionary versus dynamical time scales for the evolution of the central stars of planetary nebulae
    The disagreement between evolutionary and dynamical time scales for the evolution of the central stars of planetary nebulae (CSPN) through the H-R diagram is...
