The radio lighthouse CU Virginis: the spindown of a single main sequence star
C. Trigilio, P. Leto, G. Umana +2
The fast rotating star CU Virginis is a magnetic chemically peculiar star with an oblique dipolar magnetic field. The continuum radio emission has been interpreted as gyrosyncrotro…
ATCA observations of the very young Planetary Nebula SAO 244567
G. Umana, C. Trigilio, L. Cerrigone +2
The radio emission from the youngest known Planetary nebula, SAO244567, has been mapped at 1384, 2368, 4800, 8640, 16832 and 18752 MHz by using the Australian Telescope Compact Arr…
Millimeter observations of Planetary Nebulae: a contribution to the Planck pre-launch catalogue
G. Umana, P. Leto, C. Trigilio +5
We present new millimetre 43 GHz observations of a sample of radio-bright Planetary Nebulae. Such observations were carried out to have a good determination of the high-frequency r…
IC 4406: a radio-infrared view
L. Cerrigone, J. L. Hora, G. Umana +1
IC 4406 is a large (about 100'' x 30'') southern bipolar planetary nebula, composed of two elongated lobes extending from a bright central region, where there is evidence for the p…
IC 4406: a radio-infrared comparison
L. Cerrigone, J. L. Hora, G. Umana +1
IC 4406 is a large (about 100'' x 30'') southern bipolar planetary nebula, composed by two elongated lobes, extending from a bright central region, where there is evidence for the…
Radio and Infrared observations of Transition Objects
L. Cerrigone, J. L. Hora, G. Umana +1
Observing objects in transition from pre- to young Planetary Nebula (PN), when the central star radiation starts to excite the envelope, can help us to understand the evolution of…
