Coherent deflection pattern and associated temperature enhancements in the near-Sun solar wind
R. Laker, T. S. Horbury, L. D. Woodham +2
Measurements of transverse magnetic field and velocity components from Parker Solar Probe have revealed a coherent quasi-periodic pattern in the near-Sun solar wind. As well as bei…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
Magnetic field spectral evolution in the inner heliosphere
Nikos Sioulas, Zesen Huang, Chen Shi +23
Parker Solar Probe and Solar Orbiter data are used to investigate the radial evolution of magnetic turbulence between au. The spectrum is studied as…
Switchback Deflections Beyond the Early Parker Solar Probe Encounters
R. Laker, T. S. Horbury, L. Matteini +4
Switchbacks are Aflvénic fluctuations in the solar wind, which exhibit large rotations in the magnetic field direction. Observations from Parker Solar Probe's (PSP's) first two sol…
The In Situ Signature of Cyclotron Resonant Heating
Trevor A. Bowen, Benjmin D. G. Chandran, Jonathan Squire +9
The dissipation of magnetized turbulence is an important paradigm for describing heating and energy transfer in astrophysical environments such as the solar corona and wind; howeve…
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…
A solar source of Alfvénic magnetic field switchbacks: {\em in situ} remnants of magnetic funnels on supergranulation scales
S. D. Bale, T. S. Horbury, M. Velli +17
One of the striking observations from the Parker Solar Probe (PSP) spacecraft is the prevalence in the inner heliosphere of large amplitude, Alfvénic magnetic field reversals terme…
Plasma Properties, Switchback Patches and Low -Particle Abundance in Slow Alfvénic Coronal Hole Wind at 0.13 au
Thomas Woolley, Lorenzo Matteini, Michael D. McManus +8
The Parker Solar Probe (PSP) mission presents a unique opportunity to study the near-Sun solar wind closer than any previous spacecraft. During its fourth and fifth solar encounter…
Signatures of coronal hole substructure in the solar wind: combined Solar Orbiter remote sensing and in situ measurements
T. S. Horbury, R. Laker, L. Rodriguez +21
Context. The Sun's complex corona is the source of the solar wind and interplanetary magnetic field. While the large scale morphology is well understood, the impact of variations i…
Multi-spacecraft Study of the Solar Wind at Solar Minimum: Dependence on Latitude and Transient Outflows
