Magnetic activity in interbinary regions

Abstract

Stellar activity is conventionally viewed as a scaled up version of the solar activity. In active stars - flare stars and RS CVn binaries — one significant difference from the solar activity is the possibility of the conversion of the magnetic energy into electromagnetic energy in the interbinary regions. We show that the magnetic activity in the interbinary region can explain 1) the high temperature component of the coronae of the RS CVn binaries, 2) fast transient X-ray emission from active stars and 3) quiescent and flaring radio emission in active stars. We further show that magnetic activity in the low density interbinary regions is an attractive sight for other high energy phenomena like gamma ray bursts and acceleration of cosmic rays.
