Plasma Interaction at Io

Detailed description

This projects deals with global simulations of Io's interaction with the plasma torus by means of single-species hybrid model. Simulation set contains three hybrid simulations with variable mass loading rates and charge exchange rates. Analysis of the simulation results is published by Sebek et al., J. Geophys. Res. Space Physics, 121, pp. 7514-7534, 2016, doi: 10.1002/2016JA022477

Io's neutral atmosphere has a radial profile
n(R)=n_atm*( W_int*exp(-(R-R_Io)/H_atm) + W_ext/R^2)
here n_atm is neutral density at the surface. It governs probability of charge exchange and thus total charge exchange rate. Mass loading rate is prescribed in the simulation by the value of parameter Q_ml.

Coordinate system is IPhiOmega where the X axis is parallel to plasma flow, the Y axis is in radial direction towards Jupiter and the Z axis completes right-handed system.

Background plasma conditions correspond to flyby I0 of Galileo spacecraft around Io. Background magnetic field has magnitude B_0=1,840 nT. Background plasma has number density n_0=3,500 cm^-3, temperature T=120eV and flows at velocity 57 km.s^-1 relative to Io. We assume one plasma species, singly ionized ions with mass m_i=22m_p.
