Radio characteristics of the very young Planetary Nebulae SAO244567
C. Trigilio, G. Umana, L. Cerrigone
The radio emission from the youngest known Planetary nebula, SAO244567, has been mapped at 20,13, 6, 3.6 and 1.2 cm by using the Australian Telescope Compact Array (ATCA). These ob…
A new sample of young Planetary Nebulae
G. Umana, L. Cerrigone, C. Trigilio +1
Despite of numerous efforts, the stage from Asymptotic Giant Branch (AGB) to Planetary Nebulae (PN) is a poorly understood phase of stellar evolution. We have therefore carried out…
The Luminosity Function of PNe with different morphology
L. Magrini, R. L. M. Corradi, P. Leisy +3
We have analyzed the behaviour of various parameters of PNe in the Magellanic Clouds (MCs) and the Galaxy as a function of their morphology. The luminosity function of different mo…
