High-resolution far ultraviolet spectrum of electron-excited SO2
Ajello, Joseph; Bhardwaj, Anil; Vatti Palle, Prahlad
The high-resolution UV capabilities (λ/Δλ = 105) of the Hubble Space Telescope (HST) equipped with the Space Telescope Imaging Spectrograph (STIS) reflects a need for a high-resolution laboratory UV spectral data base for comparison with observation. For the purpose of interpreting the astronomical observations of Io by HST the electron…
Conjugate comparison of Super Dual Auroral Radar Network and Cluster electron drift instrument measurements of E × B plasma drift
Balogh, A.; Tsyganenko, N. A.; Quinn, J. M. +6 more
Much of our current understanding of magnetospheric electrodynamics is based on the assumption that magnetic field lines often behave as electrostatic equipotentials. This assumption has allowed hemispheric patterns of ionospheric convection to be interpreted in terms of the large-scale circulation of plasma in the magnetosphere. However, the exte…
Magnetic signatures of Jupiter's bow shock during the Cassini flyby
Dougherty, Michele K.; Crary, F.; Young, D. T. +1 more
The bow shock crossings detected during the Cassini flyby of Jupiter occur at positions which imply that Jupiter's bow shock was relatively inflated during the early (before 2001, Day 3) and late (after 2001, Day 40) periods of the encounter. A variety of magnetic shock signatures are seen, corresponding to a wide range (15-75 degrees) in the angl…
Cassini Plasma Spectrometer electron measurements close to the magnetopause of Jupiter
Coates, A. J.; Linder, D. R.; Young, D. T. +2 more
During late 2000 and early 2001 the Cassini satellite made a flyby of Jupiter en route to Saturn. The flyby speed was about 20 km/s, and the trajectory brought the spacecraft through the magnetosheath on the afternoonside. The Cassini Plasma Spectrometer (CAPS) instrument, consisting of two ion sensors and an electron spectrometer, was thus able t…
Source characteristics and radiation mechanism of Jovian anomalous continuum
Misawa, H.; Tsuchiya, F.; Morioka, A. +2 more
We investigate the characteristics of the Jovian anomalous continuum (JAC) in interplanetary space and in the magnetosheath, using Ulysses observations. Some new source characteristics of JAC were obtained in addition to those found by previous authors [e.g., , 1998]. JAC tends to occur when the solar wind dynamic pressure decreases after a rapid …
Field-aligned current distribution in the transition current system
Belenkaya, Elena S.; Alexeev, Igor I.; Clauer, C. Robert
The interactions of coronal mass ejections with the Earth's magnetosphere are interesting because they often lead to extreme forcing of magnetospheric convection. Here we consider the initial interaction of a CME with the magnetosphere for the specific case in which there is a sharp increase in the dynamic pressure (interplanetary shock) that is a…
Cassini/Huygens flyby of the Jovian system
Lebreton, Jean-Pierre; Matson, Dennis L.; Spilker, Linda J. +2 more
This is an introduction to the series of 15 papers that follow. These report scientific results from the fields-and-particles instruments on Cassini/Huygens. For these works, their data acquisition started as early as 16 months before the passage by Jupiter and, for some, continued up to the approach to Saturn. The flyby of Jupiter provided a grav…
Radio and multiwavelength evidence of coronal loop eruption in a flare-coronal mass ejection event on 15 April 1998
Huang, Guang-Li
A typical flare-coronal mass ejection (CME) event is studied at the initial time and position of the flare and CME. The photospheric magnetic configuration consists of two main polarities (dipolar structure) with some emerged new polarities, similar to a quadrupolar structure, during the event. The coronal loops in soft X-ray and EUV images show t…
