Scientific paper

The Giotto mission to Comet Halley discovered a magnetic cavity surrounding the nucleus in which the magnetic field strength was apparently zero. The boundary of the cavity, the ionopause, occurred at 4760 km (3840 km) and the maximum magnetic field strength was about 55 nT (65 nT), thousands of km outside the rather sharply defined transition to zero field on the inbound (outbound) part of the trajectory. A simple model is used here to show that such a magnetic field structure can be explained as being largely the result of ion-neutral friction rather than simple pressure balance alone.
