The solar wind is frequently perturbed by transient structures (magnetic folds, jets, waves and flux-ropes) that propagate away from the Sun over a large range of heliocentric distances. Parker Solar Probe has detected a large number of these at small heliocentric distances, together with surprisingly large solar wind rotation rates. Sun-to-spacecraft connectivity analysis shows that a large...
Despite studying the kinematics of Coronal Mass Ejections (CMEs), the main challenges faced in this area are due to projection effects and lack of information in the inner corona. We have tried to improve on these shortcomings by implementing the Graduated Cylindrical Shell (GCS) model to the pair of images taken by COR-1 and COR-2 on-board STEREO-A/B, and studied their initial 3D evolution....
Ionospheric ions (mainly H+, He+ and O+) escape from the ionosphere and populate the Earth’s magnetosphere. The ionospheric population is variable, and it makes significant contributions to the magnetospheric mass density in key regions where magnetic reconnection is at work. Solar wind – magnetosphere coupling occurs primarily via magnetic reconnection, a key plasma process that enables...
Magnetic clouds are large-scale transient structures in the solar wind with low plasma β, low-amplitude magnetic field fluctuations, and twisted field lines with both ends often connected to the Sun. We analyse the normalised cross helicity, σc, and residual energy, σr, in magnetic clouds observed at sub-1 au heliocentric distances by Parker Solar Probe (PSP), and compare to clouds observed at...
To better understand the solar wind dynamic interactions with Coronal Mass Ejections (CMEs), we examine the effect of magnetic erosion on to the well-known aerodynamic drag force acting on CMEs. In particular, we consider the interplay between reconnection with the ambient solar wind and the virtual mass component of the drag equation. We quantify the effect of magnetic reconnection, which...
The nature of the slow solar wind, continuous or intermittent flow, is still debated; coronagraphs and heliospheric imagers regularly observe a spectrum of transient slow wind flows; e.g. instance blobs, jets. etc. A standard tool for the study of such flows, is the display of intensity as a function of time and elongation along a given direction, which is called a J-map. The launch of the...
