NLTE Spectral Analysis of Central Stars of PNe Interacting with the ISM
T. Rauch, F. Kerber, E. Furlan +1
The analysis of Planetary Nebulae (PNe) provides a tool to investigate the properties of their exciting central stars (CSPN) at the moment of the PN ejection as well as on the prop…

PN - ISM interaction: The observational evidence
Florian Kerber, Elise Furlan, Thomas Rauch +1
We present results of an ongoing survey of low surface brightness planetary nebulae (PNe). Using both narrow-band imaging and long slit spectroscopy we have studied 15 new examples…

Survey of Large Planetary Nebulae in Decay
Thomas Rauch, Elise Furlan, Florian Kerber +1
The Planetary Nebulae (PNe) return nuclear processed stellar material back to the interstellar medium (ISM) and thus have an important influence on the chemical evolution of our Ga…
