Parker Solar Probe evidence for the absence of whistlers close to the Sun to scatter strahl and regulate heat flux

C. Cattell, A. Breneman, J. Dombeck +14

Using the Parker Solar Probe FIELDS bandpass filter data and SWEAP electron data from Encounters 1 through 9, we show statistical properties of narrowband whistlers from ~16 Rs to…

The role of asymmetries in coronal rain formation during thermal non-equilibrium cycles

Gabriel Pelouze, Frédéric Auchère, Karine Bocchialini +4

Context: Thermal non-equilibrium (TNE) produces several observables that can be used to constrain the spatial and temporal distribution of solar coronal heating. Its manifestations…

Strong perpendicular velocity-space in proton beams observed by Parker Solar Probe

J. L. Verniero, B. D. G. Chandran, D. E. Larson +16

The SWEAP instrument suite on Parker Solar Probe (PSP) has detected numerous proton beams associated with coherent, circularly polarized, ion-scale waves observed by PSP's FIELDS i…

Whistler waves observed by Solar Orbiter / RPW between 0.5 AU and 1 AU

M. Kretzschmar, T. Chust, V. Krasnoselskikh +29

The goal of our study is to detect and characterize the electromagnetic waves that can modify the electron distribution functions, with a special attention to whistler waves. We an…

Magnetic reconnection as a mechanism to produce multiple protonpopulations and beams locally in the solar wind

B. Lavraud, R. Kieokaew, N. Fargette +37

Context. Spacecraft observations early revealed frequent multiple proton populations in the solar wind. Decades of research on their origin have focused on processes such as magnet…

Solar Orbiter/RPW antenna calibration in the radio domain and its application to type III burst observations

A. Vecchio, M. Maksimovic, V. Krupar +18

In order to allow for a comparison with the measurements from other antenna systems, the voltage power spectral density measured by the Radio and Plasma waves receiver (RPW) on boa…

Characteristic scales of magnetic switchback patches near the Sun and their possible association with solar supergranulation and granulation

Naïs Fargette, Benoit Lavraud, Alexis Rouillard +16

Parker Solar Probe (PSP) data recorded within a heliocentric radial distance of 0.3 AU have revealed a magnetic field dominated by Alfvénic structures that undergo large local vari…

Direct evidence for magnetic reconnection at the boundaries of magnetic switchbacks with Parker Solar Probe

C. Froment, V. Krasnoselskikh, T. Dudok de Wit +20

Parker Solar Probe's first encounters with the Sun revealed the presence of ubiquitous localised magnetic deflections in the inner heliosphere; these structures, often called switc…

Correlation of the sunspot number and the waiting time distribution of solar flares, coronal mass ejections, and solar wind switchback events observed with the Parker Solar Probe

Markus J. Aschwanden, Thierry Dudok de Wit

Waiting time distributions of solar flares and {\sl coronal mass ejections (CMEs)} exhibit power law-like distribution functions with slopes in the range of ,…

Alfvénic versus non-Alfvénic turbulence in the inner heliosphere as observed by Parker Solar Probe

Chen Shi, Marco Velli, Olga Panasenco +20

We make use of the Parker Solar Probe (PSP) data to explore the nature of solar wind turbulence focusing on the Alfvénic character and power spectra of the fluctuations and their d…

Magnetic Imaging of the Outer Solar Atmosphere (MImOSA): Unlocking the driver of the dynamics in the upper solar atmosphere

H. Peter, E. Alsina Ballester, V. Andretta +20

The magnetic activity of the Sun directly impacts the Earth and human life. Likewise, other stars will have an impact on the habitability of planets orbiting these host stars. The…
