1. Plasma and Dust around Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko
Abstract : Saturn's moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. READ MORE

3. Ion dynamics and structure of collisionless shocks in space
Abstract : Shock waves form when supersonic flows encounter an obstacle. Like in regular gases, shock waves can form in a plasma - a gas of electrically charged particles. Shock waves in plasmas where collisions between particles are very rare are referred to as collisionless shock waves. READ MORE

4. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts
Abstract : High-speed plasma flows (jets) are ubiquitous phenomena in the visible Universe. When the fast plasma flow encounters the ambient plasma at rest, it forms a front where its kinetic energy is dissipated. At the jet front, charged particles gain energy from the electromagnetic fields through heating and acceleration. READ MORE

5. Electrostatic plasma waves associated with collisionless magnetic reconnection : Spacecraft observations
Abstract : Magnetic reconnection is a fundamental plasma process where changes in magnetic field topology result in explosive energy conversion, plasma mixing, heating, and energization. In geospace, magnetic reconnection couples the Earth’s magnetosphere to the solar wind plasma, enabling plasma transport across the magnetopause. READ MORE
