The induced magnetosphere of comet Halley: 4. Comparison of in situ observations and numerical simulations
A comprehensive comparison between the results of a multiscale three-dimensional adaptive MHD model of the comet Halley magnetosphere and in situ observations by the Giotto mission is presented. ItExpand

The induced magnetosphere of comet Halley: Interplanetary magnetic field during Giotto Encounter
Direction of the interplanetary magnetic field (IMF) which governs the orientation of the Halley's magnetosphere was restored by using Giotto magnetic field data. The Giotto trajectory was a twistedExpand

The induced magnetosphere of comet Halley: 3. The plasma kinematics
The plasma velocity in the magnetosphere of comet Halley is calculated by using the displacement of magnetic field lines during the Giotto flyby. The obtained profile is in good agreement with thatExpand

Magnetic field and electric current density distribution in the geomagnetic tail, based on Geotail data
Analysis of Geotail magnetic data enables us to reveal the antisunward electric current flowing along the tail axis. To our knowledge, observation of this current has not been reported yet.Expand

Induced magnetosphere of comet Halley: 2. Magnetic field and electric currents
An induced magnetosphere of a comet rotates around the Sun-comet line along with the interplanetary magnetic field (IMF) vector. During the Giotto flyby near comet Halley the direction of the IMFExpand

Effects of the interaction between plasma and neutrals on the stability of the cometary ionopause
It is pointed out that plasma in the cometary ionosphere is collisionally coupled to neutrals which flow out from the nucleus. The present study is concerned with the effects of this coupling on theExpand

Fine structure of the diamagnetic cavity boundary in comet Halley
[1] We calculated the electric current density in the diamagnetic cavity boundary layer (DCBL) using magnetic field data obtained during the Giotto mission to comet Halley. This current possessesExpand

Instability of a comet ionopause: Consequences of collisions and compressibility
We have analyzed the stability of a contact surface located at the ram pressure balance position in a comet coma ionosphere in the presence of collisions between ions and neutrals and finiteExpand

A Giotto/cometary dust interaction event near the diamagnetic cavity boundary
A new scenario is suggested in order to explain the burst of particles observed by Giotto near the Halley ionopause. According to this scenario, an impact of a cometary dust particle against theExpand
