Effects of Background Solar Wind and Drag Force on the Propagation of Coronal-mass-ejection-driven Shocks

Chin-Chun Wu, Kan Liou, Brian E. Wood, Lynn Hutting • The Astrophysical Journal (2024)

The propagation of interplanetary shocks, particularly those driven by coronal mass ejections (CMEs), is still an outstanding question in heliophysics and space weather forecasting. Here, we address the effects of the ambient solar wind on ...

On the Anisotropic Velocity Distribution of Newborn Pickup Ions in the Heliosheath

Senbei Du, Merav Opher, Marc Kornbleuth • The Astrophysical Journal Letters (2025)

The evolution of the velocity distribution of pickup ions is crucial for understanding the energetic neutral atom (ENA) fluxes observed by Interstellar Boundary Explorer. Pickup ions in the heliosheath contain two main components: those tra...

Identification of periodic density structures in Solar Orbiter data: Helical structures and flux ropes

Katsavrias C., Di Matteo S., Chhiber R., Kepko L. et al. • Astronomy & Astrophysics (2026)

Context. Quasi-periodic density structures (PDSs) are quasiperiodic variations in the solar wind density that range from a few minutes to a few hours. They are trains of advected density structures with radial length scales LR ≈ 100 − 10 00...

Solar‐Wind Triggering of Substorm Onset During the May 2024 Superstorm: Coordinated Global Observations and Simulations

Yong Ren, Minghui Zhu, Lei Dai, Walter Gonzalez et al. • Geophysical Research Letters (2026)

Abstract Substorms are often described by a loading‐unloading cycle, where onset follows gradual accumulation of solar wind magnetic flux in the magnetosphere. Yet observations indicate that intense substorms can also be directly driven, th...

Distribution and Abundance of Solar Wind‐Derived Water in Chang'E‐5 Core Samples and Its Implications

Heng‐Ci Tian, Jialong Hao, Yangting Lin, Yuchen Xu et al. • Geophysical Research Letters (2024)

Abstract Knowledge regarding the abundance and distribution of solar wind (SW)‐sourced water (OH/H2O) on the Moon in the shallow subsurface remains limited. Here, we report the NanoSIMS measurements of H abundances and D/H ratios on soil gr...

Magnetic Reconnection–driven Energization of Protons up to ∼400 keV at the Near-Sun Heliospheric Current Sheet

M. I. Desai, J. F. Drake, T. Phan, Z. Yin et al. • The Astrophysical Journal Letters (2025)

We report observations of direct evidence of energetic protons being accelerated above ∼400 keV within the reconnection exhaust of a heliospheric current sheet (HCS) crossing by NASA’s Parker Solar Probe (PSP) at a distance of ∼16.25 solar ...

Shocklets and Short Large Amplitude Magnetic Structures (SLAMS) in the High Mach Foreshock of Venus

Glyn A. Collinson, Heli Hietala, Ferdinand Plaschke, Tomas Karlsson et al. • Geophysical Research Letters (2023)

Abstract Shocklets and short large‐amplitude magnetic structures (SLAMS) are steepened magnetic fluctuations commonly found in Earth's upstream foreshock. Here we present Venus Express observations from the 26th of February 2009 establishin...
