Modeling comet 1P/Halley's plasma environment using multifluid MHD
Abstract
Observations by ESA's Giotto spacecraft at comet 1P/Halley on March 14, 1986, allowed a detailed glance into the interaction between the neutral gas coma and the solar wind. For a highly productive comet such as 1P/Halley the plasma environment is remarkably diverse when probed at various cometocentric distances. We apply a global scale multifluid magnetohydrodynamics (MHD) approach in which the individual plasma components are treated as a set of coupled magnetized fluids ([1], [2]). This is a continuation of our previous work using a single species model ([3], [4]) and provides insight on some of the involved dynamical processes that might otherwise only be accessible by Monte Carlo Hybrid-type models.
