Solar cycle dependence of scaling in solar wind fluctuations [PDF]
, 2008 In this review we collate recent results for the statistical scaling properties of fluctuations in the solar wind with a view to synthesizing two descriptions: that of evolving MHD turbulence and that of a scaling signature of coronal origin that ...

Impulsively Excited Quasiperiodic Fast-propagating Waves in the Solar Corona
The Astrophysical JournalQuasiperiodic fast-propagating (QFP) waves excited by an impulsive, spatially localized velocity perturbation in a curved coronal loop are investigated with three-dimensional numerical simulations.

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS
Radio Science, Volume 61, Issue 8, August 2026.Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...

On the Relationship between Solar Spicules and Propagating Coronal Disturbances: The Role of Shocks
The Astrophysical JournalSpicules and propagating coronal disturbances (PCDs) are ubiquitous dynamic features of the solar atmosphere, yet their physical connection remains an open question of paramount importance to the mass and energy transport in the solar atmosphere.

Space Weather, Volume 24, Issue 8, August 2026.Abstract Auroral precipitation plays a key role in coupling the Magnetosphere–Ionosphere–Thermosphere system by modifying ionospheric conductance, currents, atmospheric heating, and upper‐atmospheric dynamics. Leveraging 17 years of electron spectrum data from the Defense Meteorological Satellite Program (DMSP), we developed a Machine Learning‐based ...

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops
The Astrophysical JournalDecayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (

Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt
Space Weather, Volume 24, Issue 8, August 2026.Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

MHD mode conversion of fast and slow magnetoacoustic waves in the solar corona [PDF]
, 2010 There are three main wave types present in the Sun’s atmosphere: Alfvén waves and fast and slow magnetoacoustic waves. Alfvén waves are purely magnetic and would not exist if it was not for the Sun’s magnetic field.

Mode Conversion of a Solar Extreme-ultraviolet Wave over a Coronal Cavity [PDF]
The Astrophysical Journal Letters, 2017 Abstract We report on observations of an extreme-ultraviolet (EUV) wave event in the Sun on 2011 January 13 by Solar Terrestrial Relations Observatory and Solar Dynamics Observatory in quadrature. Both the trailing edge and the leading edge of the EUV wave front in the north direction are reliably traced, revealing generally compatible ...
