Abstract:
The physical mechanisms that produce the slow solar wind are still highly debated. Parker Solar Probe's (PSP's) recent solar encounters during Solar Orbiter’s (SolO) cruise phase provide new opportunities to relate in situ measurements of the nascent slow solar wind with white-light images of the solar corona. We exploit data taken by the Solar and Heliospheric Observatory, the Solar TErrestrial RElations Observatory (STEREO), and the Wide Imager on Solar Probe to study the connection between real and pseudo-streamer flows with high-density plasma measured by the different spacecraft. We exploit these images to classify the different types of slow winds measured by PSP and SolO and investigate the magneto-plasma properties of these different winds. In this presentation a particular focus will be put on the interpretation of the high-cadence measurements taken by the Proton-Alpha Sensor on Solar Orbiter.
