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…
How is really decelerating the expansion of SN1993J?
J. M. Marcaide, A. Alberdi, M. A. Perez-Torres +14
SN1993J is to date the radio supernova whose evolution has been monitored in greatest detail and the one which holds best promise for a comprehensive theoretical-observational anal…
Coherent radio emission from the magnetic chemically peculiar star CU Virginis
C. Trigilio, P. Leto, F. Leone +2
Radio observations of the magnetic chemically peculiar star CU Vir, carried out with the VLA in three different days, show that the radio emission at 20 cm is characterized by a st…
Resolving the radio nebula around beta Lyrae
G. Umana, P. F. L. Maxted, C. Trigilio +3
In this paper we present high spatial resolution radio images of the puzzling binary system beta Lyrae obtained with MERLIN at 5 GHz. We find a nebula surrounding the binary with a…
