Plasma Waves near the Electron Cyclotron Frequency in the near-Sun Solar Wind
David M. Malaspina, Jasper Halekas, Laura Bercic +17
Data from the first two orbits of the Sun by Parker Solar Probe reveal that the solar wind sunward of 50 solar radii is replete with plasma waves and instabilities. One of the most…
