Morphologies of the Nebulae around "born-again" Central Stars of Planetary Nebulae
S. Kimeswenger, A. A. Zijlstra, P. A. M. van Hoof +5
While in the past spherodicity was assumed, and still is used in modeling of most nebulae, we know now that only a small number of planetary nebulae (PNe) are really spherical or a…
Symmetry and Asymmetry in "born again" Planetary Nebulae
S. Kimeswenger, A. A. Zijlstra, P. A. M. van Hoof +4
While in the past spheroidicity was assumed, and still is used in modeling of most nebulae, we know now that only a small number of planetary nebulae (PNe) are really spherical or…
The enigma of the oldest `nova': the central star and nebula of CK Vul
M. Hajduk, Albert A. Zijlstra, P. A. M. van Hoof +9
CK Vul is classified as, amongst others, the slowest known nova, a hibernating nova, or a very late thermal pulse object. Following its eruption in AD 1670, the star remained visib…
Current Development of the Photo-Ionization Code Cloudy
P. A. M. van Hoof, P. G. Martin, G. J. Ferland
This paper describes the most important differences between Cloudy 90 and Cloudy 94, the most recent upgrade of the code which has now been posted on the WWW. It also describes the…
Measuring angular diameters of extended sources - I. Theory
P. A. M. van Hoof
When measuring diameters of partially resolved sources like planetary nebulae, H II regions or galaxies, often a technique called gaussian deconvolution is used. This technique yie…
Radio and Infrared Emission from a [WC]-Type Planetary Nebula in the LMC
Albert A. Zijlstra, Peter A. M. van Hoof, Jessica M. Chapman +1
Radio continuum emission has been detected from a planetary nebula in the Large Magellanic Cloud: this is the first radio continuum detection for any planetary nebula outside our g…
