Parker Solar Probe is today the first mission that has literally penetrated into the solar atmosphere. Since its launch in 2018 the mission has already revolutionized our perception of the solar wind. Our team at the LPC2E (Orléans) is responsible for a magnetic field sensor that is the first to probe the solar wind at high frequencies, between 10 kHz and 1 MHz. The first observations made by that instrument reveal surprising results such as the magnetic signature of type III bursts and dust impacts.
This PhD project aims at exploring these high-frequency magnetic signatures and constrain the physical models that explain their origin. This is an exploratory study with a mix of data analysis (involving many different approaches, including some machine learning) using different in situ and remote sensing instruments, and theoretical modelling.
