Abstract:
We present and discuss the observations carried out by the FIELDS instrument suite on Parker Solar Probe in the newly explored regions extending inside 30 Solar Radii from Sun center at the dawn of the new solar cycle. We will illustrate the main features of the magnetic and electric fields observed, their source regions on the Sun, and the nature and characteristics of the turbulent fluctuations as a function of the plasma parameters. We will also describe the radio bursts observed and assess how the FIELDS measurements so close to our star alter our picture of coronal heating and solar wind acceleration, solar wind origins, and the generation and acceleration of energetic particles from the Sun.
