Magnetic field observations in comet Halley's coma

The influence of negatively charged heavy ions on the kinetic Alfven wave in a cometary environment

“…Specifically, Alfvenic turbulence was detected in the magnetic field Smith 1986a, 1986b) and in the electron distribution (Gosling et al 1986) at comet Giacobini-Ziner by the ICE spacecraft. Similar turbulence was also detected by Giotto (Neubauer et al 1986) and Vega (Reidler et al 1986) spacecrafts at comet Halley. In addition to these observations, Alfvenic turbulence was also observed in the solar wind protons and alpha particles, where the fluctuations were not only seen in the plasma velocity as expected for simple Alfven waves, but also in the density and temperature as Giotto approached comet Halley (Johnstone et al 1987).…”

Kinetic Alfven Waves Excited by Cometary Newborn Ions with Large Perpendicular Energies

“…Specifically, Alfvenic turbulence has been detected in the magnetic field [6,7] and in the electron distribution [8] at comet Giacobini-Ziner by the ICE (international cometary explorer) spacecraft. Similar turbulence has also been detected by spacecrafts Giotto [9] and Vega [10] at comet Halley. In addition to these observations, Alfvenic turbulence was also observed in the solar wind protons and alpha particles, where the fluctuations appeared not only in the plasma velocity as expected for simple Alfven waves, but also in the density and temperature as Giotto approached comet Halley [11] .…”

Dispersion characteristics of kinetic Alfven waves in a multi-ion plasma

“…Such Alfvenic turbulence has been detected in the magnetic field [28] and the electron distribution [29] at the comet Giacobini-Ziner by the ICE spacecraft. Similar turbulence was also detected by the Giotto [30] and Vega [31] spacecrafts at comet Halley.…”
