Bursty synchrotron intensity variations of Jovian 6-cm radio emissions and Jupiter's quasi-periodic polar activities
Abstract
With reference to Jupiter's south polar quasi-periodic 40-50 min (QP-40) activities and the model scenario for global QP-40 magneto-inertial oscillations of the Jovian inner radiation belt (IRB), we validate relevant predictions and confirmations by amassing empirical evidence from Ulysses, Cassini, Chandra, Galileo, XMM-Newton and the Advanced Composition Explorer for Jupiter's north polar QP-40 activities. We report ground 6-cm radio observations of Jupiter by the Urumqi 25-m telescope for synchrotron intensity bursty variations of the Jovian IRB and show their likely correlations with the recurrent arrival of high-speed solar winds at Jupiter.
