On the diamagnetic effect associated with the ion pile-up region in the coma of comet Halley

Neubauer, F. M.; Israelevich, P. L.; Ershkovich, A. I.

The ion pile-up region in the comet Halley ionosphere observed on the inbound leg of the Giotto trajectory is accompanied by a decrease of the magnetic field strength. This magnetic field dip is explained by means of a diamagnetic effect of the plasma density increase in the pile-up region. Maximum of the plasma pressure seems to coincide with the…
