An overview of the anisotropy telescope observations of MeV ions during the Ulysses Jupiter encounter
Balogh, A.; Forsyth, R. J.; Cowley, S. W. H. +4 more
Observations of ∼ MeV ions obtained in Jupiter's magnetosphere with the COSPIN Anisotropy Telescope experiment during Ulysses' encounter with Jupiter in February 1992 are presented. Ulysses is the fifth spacecraft to have visited Jupiter's magnetosphere, all of which approached Jupiter from the mid-morning sector close to the equatorial plane. Uly…
The charge state of helium in the Jovian magnetosphere: a possible method to determine it
Krupp, N.; Keppler, E.
Ion measurements from the EPAC instrument on board the Ulysses spacecraft inside the Jovian dayside magnetosphere in February 1992 are reported. Energy/charge ( E/q) spectra for protons (0.5-1.0 MeV) and different ions (helium, oxygen and sulphur) in the energy range 0.4-9.0 MeV N -1 are concentrated on. In agreement with the earlier wo…
Energetic ion and electron observations at Jupiter's dayside magnetopause: implications for magnetopause location and boundary coupling processes
Balogh, A.; Forsyth, R. J.; Cowley, S. W. H. +7 more
An analysis is presented of the fluxes and anisotropies of energetic (MeV) ions and electrons measured by instruments of the COSPIN package during the first inbound traversal of the Jovian dayside magnetospheric boundary region by the Ulysses spacecraft in February 1992. The aim of the study is to elucidate the nature of the multiple structures ob…
Comparison of the wave energy transport at comets p/Halley and p/Giacobini-Zinner
Tsurutani, B. T.; Glassmeier, K. -H.; Neubauer, F. M. +2 more
Using magnetic field, plasma density and flow observations from spacecraft flybys of two comets, Elsässer variables are determined in order to study wave propagation directions. The inbound path of the Giotto spacecraft flyby of comet p/Halley is investigated outside the bow shock (between 10:36 and 19:11 UT on March 13, 1986, corresponding to dis…
Numerical simulations of non-adiabatic particle motions in the Jovian magnetosphere; comparisons with Ulysses observations
Keppler, E.; Korth, A.; Quenby, J. J. +3 more
The Ulysses encounter with Jupiter gave a unique opportunity for the study of ions in the Jovian day side in the range 0.3 < ( E/nuc) < 6 MeV. The EPAC experiment has already provided a wealth of interesting results concerning the composition and the anisotropies in the magnetosphere (Krupp et al., Planet. Space Sci.41, 953, 1993), however a…
