First direct observation of a torsional Alfvén oscillation at coronal heights

P. Kohutova, E. Verwichte, C. Froment

Torsional Alfvén waves are promising candidates for transport of energy across different layers of the solar atmosphere and have been theoretically predicted for decades. Previous…

Statistics and Polarization of Type III Radio Bursts Observed in the Inner Heliosphere

Marc Pulupa, Stuart D. Bale, Samuel T. Badman +20

We present initial results from the Radio Frequency Spectrometer (RFS), the high frequency component of the FIELDS experiment on the Parker Solar Probe (PSP). During the first PSP…

Seed Population Pre-Conditioning and Acceleration Observed by Parker Solar Probe

N. A. Schwadron, S. Bale, J. Bonnell +42

A series of solar energetic particle (SEP) events were observed at Parker Solar Probe (PSP) by the Integrated Science Investigation of the Sun (\ISOIS) during the period from April…

Switchbacks in the near-Sun magnetic field: long memory and impact on the turbulence cascade

Thierry Dudok de Wit, Vladimir V. Krasnoselskikh, Stuart D. Bale +14

One of the most striking observations made by Parker Solar Probe during its first solar encounter is the omnipresence of rapid polarity reversals in a magnetic field that is otherw…

The Enhancement of Proton Stochastic Heating in the near-Sun Solar Wind

Mihailo M. Martinović, Kristopher G. Klein, Justin C. Kasper +18

Stochastic heating is a non-linear heating mechanism driven by the violation of magnetic moment invariance due to large-amplitude turbulent fluctuations producing diffusion of ions…

First in-situ Measurements of Electron Density and Temperature from Quasi-Thermal Noise Spectroscopy with Parker Solar Probe/FIELDS

Michel Moncuquet, Nicole Meyer-Vernet, Karine Issautier +10

Heat transport in the solar corona and wind is still a major unsolved astrophysical problem. Because of the key role played by electrons, the electron density and temperature(s) ar…

Ion Scale Electromagnetic Waves in the Inner Heliosphere

Trevor Bowen, Alfred Mallet, Jia Huang +22

Understanding the physical processes in the solar wind and corona which actively contribute to heating, acceleration, and dissipation is a primary objective of NASA's Parker Solar…

The Evolution and Role of Solar Wind Turbulence in the Inner Heliosphere

C. H. K. Chen, S. D. Bale, J. W. Bonnell +21

The first two orbits of the Parker Solar Probe (PSP) spacecraft have enabled the first in situ measurements of the solar wind down to a heliocentric distance of 0.17 au (or 36 Rs).…

Magnetic connectivity of the ecliptic plane within 0.5 AU : PFSS modeling of the first PSP encounter

Samuel T. Badman, Stuart D. Bale, Juan C. Martinez Oliveros +19

We compare magnetic field measurements taken by the FIELDS instrument on Parker Solar Probe (PSP) during its first solar encounter to predictions obtained by Potential Field Source…

The role of Alfvén wave dynamics on the large scale properties of the solar wind: comparing an MHD simulation with PSP E1 data

Victor Réville, Marco Velli, Olga Panasenco +18

During Parker Solar Probe's first orbit, the solar wind plasma has been observed in situ closer than ever before, the perihelion on November 6th 2018 revealing a flow that is const…
