Properties of Magnetic Switchbacks in the Near-Sun Solar Wind
Samuel T. Badman, Naïs Fargette, Lorenzo Matteini +24
Magnetic switchbacks are fluctuations in the solar wind in which the interplanetary magnetic field sharply deflects away from its background direction so as to create folds in magn…
Surface Waves at Switchback Boundaries in the Young Solar Wind from Parker Solar Probe Observations
Kyung-Eun Choi, Oleksiy V. Agapitov, Nina Bizien +2
Switchbacks (SBs) are localized magnetic field deflections in the solar wind, marked by abrupt changes in the magnetic field direction relative to the ambient solar wind. Observati…
Data Fusion of Total Solar Irradiance Composite Time Series Using 41 Years of Satellite Measurements
Jean-Philippe Montillet, Wolfgang Finsterle, Gael Kermarrec +4
Since the late 1970s, successive satellite missions have been monitoring the sun's activity and recording the total solar irradiance (TSI). Some of these measurements have lasted f…
Sub-Alfvenic Solar Wind observed by PSP: Characterization of Turbulence, Anisotropy, Intermittency, and Switchback
R. Bandyopadhyay, W. H. Matthaeus, D. J. McComas +18
In the lower solar coronal regions where the magnetic field is dominant, the Alfven speed is much higher than the wind speed. In contrast, the near-Earth solar wind is strongly sup…
Nonlinear Interactions in Spherically Polarized Alfvénic Turbulence
Trevor A. Bowen, Samuel T. Badman, Stuart D. Bale +8
Turbulent magnetic field fluctuations observed in the solar wind often maintain a constant magnitude condition accompanied by spherically polarized velocity fluctuations; these sig…
Exploring the Solar Wind from its Source on the Corona into the Inner Heliosphere during the First Solar Orbiter - Parker Solar Probe Quadrature
Daniele Telloni, Vincenzo Andretta, Ester Antonucci +68
This Letter addresses the first Solar Orbiter (SO) -- Parker Solar Probe (PSP) quadrature, occurring on January 18, 2021, to investigate the evolution of solar wind from the extend…
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…
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 ,…
Whistler wave occurrence and the interaction with strahl electrons during the first encounter of Parker Solar Probe
V. K. Jagarlamudi, T. Dudok de Wit, C. Froment +16
We studied the properties and occurrence of narrow band whistler waves and their interaction with strahl electrons observed between 0.17 and 0.26 au during the first encounter of P…
Detection of small magnetic flux ropes from the third and fourth Parker Solar Probe encounters
L. -L. Zhao, G. P. Zank, Q. Hu +22
We systematically search for magnetic flux rope structures in the solar wind to within the closest distance to the Sun of 0.13 AU, using data from the third and fourth orbits of th…
Coronal Electron Temperature inferred from the Strahl Electrons in the Inner Heliosphere: Parker Solar Probe and Helios observations
Laura Bercic, Davin Larson, Phyllis Whittlesey +17
The shape of the electron velocity distribution function plays an important role in the dynamics of the solar wind acceleration. Electrons are normally modelled with three componen…
Kinetic Scale Spectral Features of Cross Helicity and Residual Energy in the Inner Heliosphere
Daniel Vech, Justin C. Kasper, Kristopher G. Klein +17
In this Paper, we present the first results from the Flux Angle operation mode of the Faraday Cup instrument onboard Parker Solar Probe. The Flux Angle mode allows rapid measuremen…
Observations of heating along intermittent structures in the inner heliosphere from PSP data
R. A. Qudsi, B. A. Maruca, W. H. Matthaeus +22
The solar wind proton temperature at 1-au has been found to be correlated with small-scale intermittent magnetic structures, i.e., regions with enhanced temperature are associated…
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…
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
