The magnetosphere of Mercury is studied using an implicit full particle‐in‐cell simulation (PIC). We use a hybrid simulation where ions are full particles and electrons are considered as a fluid to start a PIC simulation where electrons are also particles and follow their distribution function. This approach allows us to estimate the changes introduced by the electron kinetic physics. We find that the overall macroscopic state of the magnetosphere of Mercury is little affected, but several… 



Global Ten‐Moment Multifluid Simulations of the Solar Wind Interaction with Mercury: From the Planetary Conducting Core to the Dynamic Magnetosphere

For the first time, we explore the tightly coupled interior‐magnetosphere system of Mercury by employing a three‐dimensional ten‐moment multifluid model. This novel fluid model incorporates the

A two-dimensional particle simulation of the magnetopause current layer

We have developed a 2½-dimensional (x, y, υx, υy, υz) electromagnetic code to study the formation and the stability of the magnetopause current layer. This code computes the trajectories of ion and

Interaction of Mercury with the Solar Wind

Abstract We present the structure of the hermean magnetosphere obtained by a global three-dimensional MHD simulation. The magnetic field of Mercury is strong enough to form a permanent magnetosphere

Observations and simulations of non-local acceleration of electrons in magnetotail magnetic reconnection events

Magnetic reconnection in magnetized plasmas represents a change in magnetic field topology and is associated with a concomitant energization of charged particles that results from a conversion of

Global Hybrid Simulations of the Earth's Magnetosphere

The interaction of solar wind with the Earth’s magnetosphere has turned out to be much more complex than originally thought. A major reason for this complexity and richness in the type of underlying

Global MHD simulations of Mercury's magnetosphere with coupled planetary interior: Induction effect of the planetary conducting core on the global interaction

Mercury's comparatively weak intrinsic magnetic field and its close proximity to the Sun lead to a magnetosphere that undergoes more direct space‐weathering interactions than other planets. A unique

Embedding particle-in-cell simulations in global magnetohydrodynamic simulations of the magnetosphere

We have combined global magnetohydrodynamic (MHD) simulations of the solar wind and magnetosphere interaction with an implicit particle-in-cell simulation (PIC) and used this approach to model

Kinetic instabilities in Mercury's magnetosphere: Three‐dimensional simulation results

A self‐consistent global three‐dimensional kinetic study of Mercury's magnetosphere is carried out examining waves and instabilities generated by ion temperature anisotropy and plasma flow. The

Structure of Mercury's magnetosphere for different pressure of the solar wind: Three dimensional hybrid simulations

We have carried out a self‐consistent three dimensional global hybrid simulation study examining the interaction of the solar wind with Mercury's magnetosphere. We consider two cases: one with

A multiscale study of ion heating in Earth's magnetotail

Ion heating during a substorm on 15 February 2008, starting at 0348 UT, is studied with a new approach recently described in Ashour‐Abdalla et al. (2015). The general conditions of the magnetotail
