Radio emission from Algol-type binaries. I. Results of 1992-1993 VLA survey.

UMANA G., TRIGILIO C. and CATALANO S.

Abstract (from CDS):

In this paper we report on a 5 GHz survey of 26 Algol-type binaries. Six systems were detected. We combine the new results with previously published data to derive some radio characteristics of Algols and to compare them with those of other active binaries. The radio detection rate of 30%, a factor that is somewhat smaller compared to the case of RSCVn-type, does not seem to be due to a reduced coronal activity. In fact, Algols share many similarities with the radio behavior of RS CVns and the 5GHz luminosity functions of both kind of systems look quite similar. Among the different possibilities, the high radio variability and distances, which, on average, are larger than those of RS CVns, seem to be the most reasonable explanation for the apparently reduced activity at radio wavelengths.
