Bursty Variations of Jovian 6cm Radio Emissions and Quasi-Periodic Jupiter's Polar Activities

TL;DR

This paper investigates the quasi-periodic 40-50 minute radio emissions from Jupiter's poles, validating models with multi-mission data and ground observations, revealing correlations with solar wind activity.

Contribution

It provides empirical evidence supporting the model of global QP-40 oscillations in Jupiter's inner radiation belt through multi-mission data and ground-based radio observations.

Findings

Detection of bursty 6cm radio variations correlated with solar wind arrivals.

Validation of the QP-40 oscillation model for Jupiter's polar activities.

Empirical confirmation from multiple space missions and ground observations.

Abstract

In reference to Jupiter south polar quasi-periodic 40-50 min (QP-40) activities and the model scenario for global QP-40 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 Advanced Composition Explorer for Jupiter north polar QP-40 activities. We report ground 6cm radio observations of Jupiter by Urumqi 25m 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.
