Entropy, 2021 This paper explores the spatial variations of the statistical scaling features of low to high latitude geomagnetic field fluctuations at Swarm altitude. The data for this study comes from the vector field magnetometer onboard Swarm A satellite, measured ...

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract Electromagnetic ion cyclotron (EMIC) waves are recognized as one of the primary drivers of energetic electron precipitation (EEP) into the Earth's atmosphere. A problematic discrepancy has remained between the occurrence frequency of waves in magnetic local time (MLT) and the resultant precipitation observed by satellites.

Searching for Magnetospheres around Herbig Ae/Be Stars
Universe, 2021 We describe four different approaches for the detection of magnetospheric accretion among Herbig Ae/Be stars with accretion disks. Studies of several unique objects have been carried out.

A Superposed Epoch Analysis of Two Stage Refilling in the Plasmasphere
Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract The cold, dense plasma of the plasmasphere is sourced by outflows from the ionosphere, but the refilling process is still poorly understood. Refilling may occur in stages, and studying this process is important to understanding how the ionosphere couples to the magnetosphere.

Organization of the magnetosphere during substorms [PDF]
, 2011 The change in degree of organization of the magnetosphere during substorms is investigated by analyzing various geomagnetic indices, as well as interplanetary magnetic field z-component and solar wind flow speed. We conclude that the magnetosphere self-organizes globally during substorms, but neither the magnetosphere nor the solar wind become more ...

Chaos and magnetospheric dynamics [PDF]
Nonlinear Processes in Geophysics, 1994 Abstract. Our intention in this work is to show, by using two different methods, that magnetospheric dynamics reveal low dimensional chaos. In the first method we extend the chaotic analysis for the AE index time series by including singular value decomposition (SVD) analysis in combination with Theiler's test in order to discriminate dynamical chaos ...

Deriving IMF Properties From Mars Express Heavy Pickup Ion Measurements
Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract We present Mars Express (MEX) observations of heavy pickup ions (HPUI) at Mars and a new method to derive interplanetary magnetic field (IMF) properties. The MEX HPUI measurements were organized using the upstream IMF directions measured by the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission.

Random Forest Model of Ultralow‐Frequency Magnetospheric Wave Power
Earth and Space Science, 2020 Models of magnetospheric ultralow‐frequency (ULF) waves can be used to study wave phenomena and to calculate the effect of these waves on the energization and transport of radiation belt electrons.

Main statistical properties of hectometric continuum radiation in near-Earth space
Solar-Terrestrial Physics, 2023 In this work, we have studied the recently discovered hectometric continuum radiation in near-Earth plasma. We have carried out a detailed statistical analysis of the occurrence of a hectometric continuum near Earth at distances 1.1–2 Re, where Re is the
