Radio emission from active binaries - Dr Grazia Umana Colloquium
Active binaries are one of the major classes of stellar radio sources.
I will summarize recent results from the study of this class of
stellar system in the radio domain, including spectral, high
resolution and single dish observations. In particular I will, focus
on results from the long-lasting single-dish monitoring program,
carried out with the 32m radiotelescope of C.N.R. Istituto di
Radioastronomia at Noto, of a sample of active binary stars.
I will show how radio observations have produced important information
on radio emission from active stars that have contributed to our
understanding of stellar coronae. In particular, clues on flaring
occurrence, radiation mechanism, magnetic structures morphology and
energy budget have been provided.
