Interpretation of unpolarized radio emission from RS CVn stars.
Abstract
The authors investigate the emission process and the energy budget of radio flares in RS CVn stars by applying various mechanisms to the close binary σ2CrB (HD 146361) of RS CVn type. Radio emission from this system observed with the WSRT at 21 cm is explained as synchrotron emission from electrons with Lorentz factors 3.5-3.1 in magnetic fields of strength 27 - 35 G. The energy source of the radio emitting electrons and of the previously observed X-ray gas is studied; the authors show that a solar-like filament flare forms an attractive mechanism to explain the observed energy release.
