| Zusammenfassung |
| We are developing a hybrid model of the Pluto plasma environment (HYB-Pluto) to study the
solar wind interaction with Pluto’s plasma tail to distances of 1000 Pluto radii (RP) while still
resolving the shock and/or wave features upstream of Pluto with good resolution. The
HYB-Pluto model features an extended domain and adaptable grid structure along with
important processes such as ion-neutral interactions. We present results from our first
simulations with the HYB-Pluto model that used realistic values for the solar wind bulk
properties and included He++ ions. The results show the formation of a bow shock upstream
of Pluto as well as asymmetries of ion density and bow shock in the direction of the
convection electric field. This model, along with other current models [1], will
provide tools to interpret and understand the plasma observations obtained during
expected encounter of the New Horizons spacecraft with the Pluto system in July
2015.
