A new functional form to study the solar wind control of the magnetopause size and shape
In this study a new functional form, r = r 0 [2/(1 + cos θ)] α , is used to fit. the size and shape of the magnetopause using crossings from ISEE 1 and 2, Active Magnetospheric Particle Tracer…
Subsurface Oceans on Europa and Callisto: Constraints from Galileo Magnetometer Observations

P perturbations of the external magnetic fields (associated with Jupiter's inner magnetosphere) in the vicinity of both Europa and Callisto are reported, and it is argued that these conducting layers may best be explained by the presence of salty liquid-water oceans.
Influence of solar wind on Jupiter's magnetosphere deduced from currents in the equatorial plane

Galileo is the sixth spacecraft to have visited Jupiter's magnetosphere. Among them the six spacecraft have sampled a fairly large expanse of magnetospheric local times and latitudes under varying…
Euler potential models of Jupiter's magnetospheric field

[1] The magnetotails of Jupiter and Earth are known to be hinged so that their orientation is controlled by the magnetic field of the planet at small distances and asymptotically approach the…
Probabilistic models of the Jovian magnetopause and bow shock locations

[1] New three-dimensional models of the Jovian magnetopause and bow shock were derived by combining spacecraft observations with boundary characteristics inferred from a magnetohydrodynamic (MHD)…
Modeling the size and shape of Saturn's magnetopause with variable dynamic pressure
- C. Arridge, N. Achilleos, M. Dougherty, K. Khurana, C. Russell
- Physics, Geology
- 1 November 2006
[1] The location and shape of a planetary magnetopause is principally determined by the dynamic pressure, Dp, of the solar wind, the orientation of the planet's magnetic dipole with respect to the…
Galileo magnetometer measurements: a stronger case for a subsurface ocean at Europa.
