| 摘要 | The chromospherically-active binary, V711 Tau, had been observed by using the American Very Large Array (VLA) at five bands from 1.4 to 15 GHz. During the observation, the source was undergoing an intense flare, its radio luminosity up to 1.8 x 10(18) erg s-1 Hz-1. The degree of circular polarization in the phase of the most intense flare was very small. With the decaying of the flare the flux density decreased, spectral index became smaller, spectra steeper and reversal frequency lower; the degree of circular polarization increased and its direction was dependent on frequency. These observational facts support the conclusion that the emission during intense flare is synchrotron (or synchro-cyclotron) mechanism. The magnetic intensity is about 10 G near tau = 1, the average electron energy, 4 MeV, the electron density with larger than 10 keV, 3 x 10(4)-9 X 10(4) cm-3 and the electronic energy spectrum index in power-law distribution 1.3. |
