“…Treatments of vacuum fields and the plasma-vacuum interface differ significantly from the method used by Hewett [1980], and these are the most significant contributions of this dissertation, beside parallelization of ADI. The following vacuum field and plasma-vacuum interface treatments were newly implemented: it requires more computational work for relaxation; it also erroneously enforces a curl-free current density at the plasma-vacuum interface.…”

This paper reports the results of hybrid simulations of the Mars‐solar wind interaction. The focus is on the loss rates of O+ and O2+ from the Martian ionosphere while examining the importance of including 3‐D dimensional neutral atmospheres with their associated neutral winds. The simulation loss rates are found to be in excellent agreement with loss rates reported by Lundin et al. (2013). Further, the results follow the functional form of the loss rates versus solar EUV as determined by Lundin et al. (2013). This paper will discuss numerical issues as well as the implementation of 3‐D neutral atmospheres, including neutral winds and corotation flows.

We have numerically studied the evolution of the heavy ions that expand in a cold background plasma at a large scale. Two typical collective behaviors of the heavy ions are identified with the conditions where only the traversing heavy ion's initial total mass is different. Our work has demonstrated that a difference in the initial total mass of the moving heavy ions is able to induce completely different collective behaviors of the plasma. The simulation is performed via the hybrid model, in which the ions and electrons are treated as classical particles and mass-less fluid, respectively. Due to the imbalance of the electric and magnetic force on the heavy ions, these particles will evolve into different collective patterns at the later time. These patterns manifest a rather different stopping behavior of the moving ions and an opposite drifting direction of the electron fluid at the rim of the expanding plasma. Further numerical and analytical calculations show that the imbalance depends not only on the number densities of the plasma ions, but also on the spatial variations of the magnetic fields. Our work reveals that the collective behavior of the heavy ions is highly non-linear, and the non-linearity is able to induce different phenomena in the evolution of the system at a large scale.
