Solar Energetic Particle Events in the 23rd Solar Cycle: Interplanetary Magnetic Field Configuration and Statistical Relationship with Flares and CMEs [PDF]
Solar Physics, 2013, Volume 282, Issue 2, pp.579-613, 2014 We study the influence of the large-scale interplanetary magnetic field configuration on the solar energetic particles (SEPs) as detected at different satellites near Earth and on the correlation of their peak intensities with the parent solar activity.

Ion‐Acoustic Waves and the Proton‐Alpha Streaming Instability at Collisionless Shocks
Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract Ion‐acoustic waves are routinely observed at collisionless shocks and could be an important source of resistivity. The source of instability and the effects of the waves are not fully understood. We show, using Magnetospheric Multiscale mission observations and numerical modeling, that across low Mach number shocks a large relative drift ...

Frontiers in Astronomy and Space Sciences, 2021 We investigate here the magnetic properties of a large-scale magnetic flux rope related to a coronal mass ejection (CME) that erupted from the Sun on September 12, 2014 and produced a well-defined flux rope in interplanetary space on September 14–15 ...

Effect of the interplanetary magnetic field orientation and intensity in the mass and energy deposition on the Hermean surface [PDF]
, 2016 The aim of the present study is to simulate the interaction between the solar wind and the Hermean magnetosphere. We use the MHD code PLUTO in spherical coordinates with an axisymmetric multipolar expansion of the Hermean magnetic field, to perform a set of simulations with different interplanetary magnetic field orientations and intensities.

Earth and Space Science, Volume 12, Issue 5, May 2025.Abstract This study investigates the distinctive features of the daytime equatorial E‐region ionosphere using observations of HF radar (18 MHz), ionosonde, and magnetometer at Thumba (8.5°N, 77°E, dip lat = 1.9°N), India, during the extreme geomagnetic storm of May 10–11, 2024 (minimum SYM‐H ∼ −497 nT).

Can an interplanetary magnetic field reach the surface of Venus? [PDF]
Annales Geophysicae, 2018 We address the question of whether there is a possibility of an interplanetary magnetic field reaching Venus' surface by magnetic diffusion across the ionosphere.

Effect of the exoplanet magnetic field topology on its magnetospheric radio emission [PDF]
A&A, Forthcoming article, 2018, 2018 The magnetized wind from stars that impact exoplanets should lead to radio emissions. According to the scaling laws derived in the solar system, the radio emission should depend on the stellar wind, interplanetary magnetic field, and topology of the exoplanet magnetosphere. The aim of this study is to calculate the dissipated power and subsequent radio

Structure of the Turbulent Interplanetary Magnetic Field [PDF]
The Astrophysical Journal, 2006 We show that two widely used but apparently different models of the turbulent interplanetary magnetic field are closely related. One of these is the so-called quasi-static turbulence model, in which interplanetary magnetic field fluctuations are generated at a source surface near the Sun by random transverse plasma motions (such as supergranulation at ...

Guide for Conducting “Community Challenges” in Space Physics
Earth and Space Science, Volume 12, Issue 5, May 2025.Abstract The Geospace Environment Modeling (GEM) program regularly issues “community challenges” in which researchers examine a particular space physics phenomenon or geomagnetic activity event, often running numerical models to assess dominant processes and understand the timing and relationship of observed signatures.
