Observational Analysis of Magnetic Flux Ropes Using Parker Solar Probe Data and Other Spacecraft.

Interplanetary coronal mass ejections (ICMEs) sometimes contain magnetic clouds (MCs) that are identifiable by an enhanced magnetic field, smooth change in the magnetic field components, depressed proton temperature and plasma beta. These MCs are further described as magnetic flux rope structures (MFRs) with a helical magnetic field around an axis. The study of helical magnetic field structures like MFRs is of great importance as they play an essential role in fundamental plasma processes such as magnetic reconnection in Space and at Earth’s magnetosphere. MFRs have been extensively studied within the interplanetary space between Sun and Earth and beyond. With PSP travelling closer to the Sun than any spacecraft before, we sought to identify MFRs at unprecedented distances and connect them with other spacecraft observations in the interplanetary medium. This work then calculated relevant parameters to describe MFRs and deduced their evolution across radial and longitudinal distances.
