Differences between CME-driven storms and CIR-driven storms [PDF]

, 2006
Twenty one differences between CME-driven geomagnetic storms and CIR-driven geomagnetic storms are tabulated. (CME-driven includes driving by CME sheaths, by magnetic clouds, and by ejecta; CIR-driven includes driving by the associated recurring high ...

Acceleration of suprathermal protons near an interplanetary shock

, 2023
Context. Interplanetary collisionless shocks are known to be sources of energetic charged particles up to hundreds of MeV. However, the underlying acceleration mechanisms are still under debate. Aims.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, Volume 2, Issue 2, June 2026.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

A multi-instrument view of tail reconnection at Saturn

, 2008
Three instances of tail reconnection events at Saturn involving the ejection of plasmoids downtail have been reported by Jackman et al. (2007) using data from Cassini’s magnetometer (MAG).

Contemporaneous Appearances of Auroral Spiral and Transpolar Arc: Polar UVI Observations and Global MHD Simulations

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract A local vortex‐structured aurora and a large‐scale transpolar arc (TPA) were contemporaneously observed by the Polar ultraviolet imager (UVI) during the late recovery phase of a substorm, and the interplanetary magnetic field (IMF) BY and BZ were negative and negative‐to‐positive. The TPA grew along the dawnside auroral oval from the nightside

Electron Acceleration in Time-dependent Kinematic Three-dimensional Magnetic Reconnection: The Role of Induced Electric Fields and Magnetic Topology

The Astrophysical Journal Supplement Series
Particle acceleration during magnetic reconnection is a key process in space physics and astrophysics, yet the direct role of induced electric fields in fully time-dependent three-dimensional (3D) topologies remains poorly quantified.

Solar and interplanetary particles re-accelerated at the solar wind termination shock [PDF]

Advances in Space Research, 1999
We consider the acceleration of solar/interplanetary particles at the solar wind termination shock, predict the expected composition and energy spectra, and discuss possible observable ...

Effects of Hot Oxygen Corona on Ion Escape From Venus‐Like Planets

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Due to the lack of a significant planetary magnetic field, the upper atmospheres of Venus‐like planets interact directly with the stellar wind. Therefore, thermal atomic oxygen in the thermosphere and hot oxygen in the corona produced by non‐thermal processes in the upper atmosphere act as a source of ion pickup loss.

An Overview of Solar Orbiter Observations of Interplanetary Shocks in Solar Cycle 25

The Astrophysical Journal Supplement Series
Interplanetary (IP) shocks are fundamental constituents of the heliosphere, where they form as a result of solar activity. We use previously unavailable measurements of IP shocks in the inner heliosphere provided by Solar Orbiter, and present a survey of
