The induced magnetosphere of comet Halley 4. Comparison of in situ observations and numerical simulations

Neubauer, F. M.; Gombosi, T. I.; Israelevich, P. L. +3 more

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. It is shown how a steady state model can describe the effects of the varying IMF direction on the cometary magnetosphere. The simulation results reproduce…
