Short-lived nuclei in the Galaxy and in the early solar system: crucial tests expected from gamma-ray line observations
Maurizio Busso, Stefano Ciprini, Francesca Marcucci
We discuss some open problems in the understanding of the Early Solar System abundances of short-lived radioactive isotopes, and the important clarification expected on this matter…
Mid-infrared photometry of carbon stars and perspectives for surveys in the Magellanic Clouds from Dome-C
Stefano Ciprini, Maurizio Busso
A preliminary analysis of the data from the MSX space infrared satellite, seems to confirm that the [8.8]-[12.5] micron color index is well correlated with the mass-loss rates in c…
Discovery, identification, and study of variability in gamma-ray point sources
M. Fiorucci, N. Marchili, G. Tosti +3
We present preliminary results of a statistical analysis obtained with a sample of blazars observed at the Perugia Astronomical Observatory since 1992. We briefly show how these st…
Synchrotron-Self Compton Spectral Evolution of PKS 2155-304
Stefano Ciprini, Gino Tosti
The high frequency peaked blazar PKS 2155-304 is one of the brightest and most intensively studied prototype of BL Lac objects. Gamma-rays from PKS 2155-304 have been detected from…
