Radial and Local Time Variations in the Thickness of Jupiter's Magnetospheric Current Sheet
Hospodarsky, G. B.; Khurana, K. K.; Paranicas, C. P. +1 more
The magnetic field observations from the Galileo, Ulysses, Voyager 1 and 2, and Pioneer 10 and 11 spacecraft are analyzed to understand the structures and thickness of the Jovian magnetospheric current sheet. Using a new technique that can determine the motion of the spacecraft relative to the current sheet, we have built the first global map of t…
Decadal and Annual Variations in Meteoric Flux From Ulysses, Wind, and SOFIE Observations
Malaspina, David; Hunziker, Silvan; Sterken, Veerle +3 more
Our solar system is filled with meteoric particles, or cosmic dust, which is either interplanetary or interstellar in origin. Interstellar dust (ISD) enters the heliosphere due to the relative motion of the sun and the interstellar flow. Interplanetary dust (IPD) comes primarily from asteroid collisions or comet sublimation, and comprises the bulk…
Pitch Angle Distribution of MeV Electrons in the Magnetosphere of Jupiter
Witasse, O.; Kollmann, P.; Nénon, Q. +3 more
The magnetosphere of Jupiter harbors the most extreme fluxes of MeV electrons in the solar system and therefore provides a testbed of choice to understand the origin, transport, acceleration, and loss of energetic electrons in planetary magnetospheres. Along this objective, the Pitch Angle Distribution (PAD) of energetic electrons may reveal signa…
Comparing and Contrasting the Properties of the Inner Heliosphere for the Three Most Recent Solar Minima
Downs, Cooper; Riley, Pete; Linker, Jon A. +2 more
The previous three solar cycles have ended in progressively more quiescent conditions, suggesting a continual slide into an ever deeper minimum state. Although the Sun's magnetic field is undoubtedly responsible for this quiescence, it is not clear how changes in its structure and strength modulate the properties of the solar wind. In this study, …
