Wave Activity in Jupiter's North Equatorial Belt From Near-Infrared Reflectivity Observations
Wong, Michael H.; Irwin, Patrick G. J.; Orton, Glenn S. +4 more
High spatial resolution images of Jupiter at 1.58-2.28 µm are used to track and characterize a wave pattern observed in 2017 at a planetocentric latitude of 14°N. The wave pattern has a wave number of 18 and spans ∼5° in latitude. One bright crest remains stationary in System III longitude, while the remaining crests move slowly westward. Th…
Magnetized Dust Clouds Penetrating the Terrestrial Bow Shock Detected by Multiple Spacecraft
Lai, H. R.; Russell, C. T.; Jia, Y. D. +1 more
Clouds of charged nanometer dust, produced in intra-meteoroid collisions and accelerated by the magnetized solar wind, twist the interplanetary magnetic field as they are accelerated. Depending on the cloud size, minutes to hours-long perturbations are observed by interplanetary spacecraft and have been termed interplanetary field enhancements (IF…
A Persistent, Large-Scale, and Ordered Electrodynamic Connection Between Saturn and Its Main Rings
Gurnett, D. A.; Dougherty, M. K.; Hospodarsky, G. B. +8 more
Auroral hiss emissions are ubiquitous in planetary magnetospheres, particularly in regions where electric current systems are present. They are generally diagnostic of electrodynamic coupling between conductive bodies, thus making auroral and moon-connected magnetic field lines prime locations for their detection. However, the role of Saturn's rin…
