六个证据反对解释木星主极光的共转执行理论

Six pieces of evidence against the corotation enforcement theory to explain the main aurora at Jupiter

Bertrand Bonfond, Zhonghua Yao, Denis Grodent

摘要:

木星紫外线极光最显著的特征是以每个磁极为中心的几乎连续不断的明亮辐射幕,称为主辐射。根据经典理论,它是由一个电流回路将动量从木星电离层传递到磁层等离子体的结果。然而,基于这些主流模型的预测最近受到了朱诺号和哈勃太空望远镜观测的挑战。在这里,我们回顾了主要的矛盾观察,揭示了它们对理论的影响,并讨论了有希望的前进道路。

英文摘要:

The most remarkable feature of the ultraviolet auroras at Jupiter is the ever present and almost continuous curtain of bright emissions centered on each magnetic pole and called the main emissions. According to the classical theory, it results from an electric current loop transferring momentum from the Jovian ionosphere to the magnetospheric plasma. However, predictions based on these mainstream models have been recently challenged by observations from Juno and the Hubble Space Telescope. Here we review the main contradictory observations, expose their implications for the theory and discuss promising paths forward.
