Planetary Nebulae - modelling and observations
(Supervision: Stefan Kimeswenger)

Work focus

Working with CLOUDY photoionization models and already reduced data.


Planetary nebulae are a spectacular final stage of most regular stars (masses between 0.8 and 8 times solar). Although it is the most frequent finale of stellar lives, it is not that well understood due to its short lifetime of about 10 000 years only. Moreover, the targets are fairly faint. Thus only with modern 8m class telescopes the spectroscopic investigation can be achieved properly.
