Classification of magnetized star--planet interactions: bow shocks, tails, and inspiraling flows [PDF]

, 2015
Close-in exoplanets interact with their host stars gravitationally as well as via their magnetized plasma outflows. The rich dynamics that arises may result in distinct observable features.

Juno Observations of Langmuir Waves in Association with Interplanetary Shocks from ~1.3 to ~5.4 au

The Astrophysical Journal Letters
Langmuir waves are often observed upstream of planetary bow shocks and interplanetary (IP) shocks. Waveform capture (WFC) measurements, obtained during Juno’s cruise phase, reveal the occurrence of Langmuir waves, as well as other wave modes, in ...

Compound electron acceleration at planetary foreshocks [PDF]

Nature Communications
Shock waves, the interface of supersonic and subsonic plasma flows, are the primary region for charged particle acceleration in multiple space plasma systems, including Earth’s bow shock, which is readily accessible for in-situ measurements.

Bridging observations and simulations: challenges in planetary bow shock studies

Planetary bow shocks provide an excellent laboratory for studying shock physics. Over the past six decades, they have been extensively investigated in situ by various satellite missions aiming to study particle behavior and fields at both macro and micro scales.

Evidence of Electron Acceleration via Nonlinear Resonant Interactions with Whistler-mode Waves at Foreshock Transients

The Astrophysical Journal, 2023
Shock waves are sites of intense plasma heating and charged particle acceleration. In collisionless solar wind plasmas, such acceleration is attributed to shock drift or Fermi acceleration but also to wave–particle resonant interactions.

Intense Whistler-mode Waves at Foreshock Transients: Characteristics and Regimes of Wave−Particle Resonant Interaction

The Astrophysical Journal, 2023
Thermalization and heating of plasma flows at shocks result in unstable charged-particle distributions that generate a wide range of electromagnetic waves. These waves, in turn, can further accelerate and scatter energetic particles. Thus, the properties

Scattering of Superthermal Ions at Shocks: Dependence on Energy

The Astrophysical Journal, 2023
Diffusive shock acceleration requires the production of backstreaming superthermal ions (injection) as a first step. Such ions can be generated in the process of scattering of ions in the superthermal tail off the shock front. Knowledge of the scattering
