Solar wind dependence of ion parameters in the earth's magnetospheric region calculated from CLUSTER observations [PDF]
, 2008 Moments calculated from the ion distributions (~0–40 keV) measured by the Cluster Ion Spectrometry (CIS) instrument are combined with data from the Cluster Flux Gate Magnetometer (FGM) instrument and used to characterise the bulk properties of the plasma

Filament Eruptions Outside of Active Regions as Sources of Large Solar Energetic Particle Events [PDF]
Proceedings of The 34th International Cosmic Ray Conference — PoS(ICRC2015), 2016 Gradual solar energetic (E > 10 MeV) particle (SEP) events are produced in shocks driven by fast CMEs, which are nearly always spatially associated with ARs. Several cases of SEP events associated with CMEs originating in large filament eruptions (FEs) from outside ARs have previously been known, but four more such cases from solar cycles 23 and 24 ...

Development and application of a global magnetic field evolution model for the solar corona [PDF]
, 2009 Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Prediction of Space Weather Events using Solar Filaments and Sound waves as Precursors
, 2023 This dissertation is an effort in adding to existing methods of predictive capability for space weather events such as coronal mass ejections (CMEs) and solar flares and to predict if these events will cause a geo-magnetic storm well in advance.

On the topology of global coronal magnetic fields [PDF]
, 2014 This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.
