Simulation of plasma interactions between comet 67P/C-G and the solar wind around perihelion

This 3D simulation models the plasma interactions between comet 67P/Churyumov-Gerasimenko and the solar wind. The simulated conditions represent those expected at 1.3 AU from the Sun, close to perihelion, where the comet is strongly active – a gas production rate of 5 × 1027 molecules/s is assumed here. The solar wind approaches from the left at ~400 km/s, carrying with it the embedded interplanetary magnetic field with a strength of about 5 nT.
