Title: Evolution of solar storms due to interplanetary interactions
Abstract: Coronal mass ejections (CMEs), a.k.a. solar storms, are the huge expulsions of magnetized plasma from the Sun. Its near-Earth properties determine the severity of associated geomagnetic storms. As the intrinsic properties of CMEs regulate CME geoeffectivness, it is worthwhile to find out what controls the CME intrinsic properties and how they evolve during interplanetary propagations. While propagating through the interplanetary medium, CMEs may interact with the large-scale interplanetary structures, significantly impacting CME’s inherent properties. Using in situ observations and analysis, we demonstrate the draping of large-scale interplanetary structures about CMEs, magnetic interactions between draped interplanetary fields and CME field lines, and the impact on CME intrinsic magnetic properties.
Short bio: Dr. Sanchita Pal, originally from India, is currently working as a postdoctoral fellow at the University of Helsinki, Finland studying solar storms and their evolutions in the Sun-Earth domain. Her research interests are investigating the solar origin of solar storms and their properties, appearances, and evolutions in the inner heliosphere as well as forecasting their geoeffectiveness.
