Interplanetary Shocks Observed from Multipoints at Venus and 1 au
The Astrophysical JournalWe present a database of 12 fast forward interplanetary (IP) shocks observed in situ by radially aligned spacecraft (Venus Express, Wind, and/or STEREO) between 2006 and 2014.

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Characterization of CME-driven shock in the interplanetary medium using type II radio bursts [PDF]
, 2017 Type II radio bursts are indirect signatures of the fast magnetosonic shock formation in the heliosphere. Those types of MHD shocks accelerate electron beams that via plasma emission mechanism produce electromagnetic radiation.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic interaction in which standing Alfvén wings form.

, 2022 International audienceInterplanetary Shocks are ubiquitous in the Solar System. They can be generated by a number of different sources, including Coronal Mass Ejections and Corotating Interaction Regions, whenever a fast stream overlays the slow ...

Three-stage Acceleration of Solar Energetic Particles Detected by Parker Solar Probe
The Astrophysical Journal LettersCoronal mass ejections (CMEs) drive powerful shocks and thereby accelerate solar energetic particles (SEPs) as they propagate from the corona into interplanetary space.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.

Propagation of Interplanetary Shocks in the Heliosphere
, 2023 Interplanetary shocks are one of the crucial dynamic processes in the Heliosphere. They accelerate particles into a high energy, generate plasma waves, and could potentially trigger geomagnetic storms in the terrestrial magnetosphere disturbing significantly our technological infrastructures. In this study, two IP shock events are selected to study the
