Using Solar Orbiter as an upstream solar wind monitor for real time space weather predictions
R. Laker, T. S. Horbury, H. O'Brien +11
Coronal mass ejections (CMEs) can create significant disruption to human activities and systems on Earth, much of which can be mitigated with prior warning of the upstream solar wi…
Multi-spacecraft observations of the structure of the sheath of an interplanetary coronal mass ejection and related energetic ion enhancement
E. K. J. Kilpua, S. W. Good, N. Dresing +18
Sheaths ahead of coronal mass ejections (CMEs) are large heliospheric structures that form with CME expansion and propagation. Turbulent and compressed sheaths contribute to the ac…
Flux ropes and dynamics of the heliospheric current sheet
V. Réville, N. Fargette, A. P. Rouillard +19
Context. Solar Orbiter and PSP jointly observed the solar wind for the first time in June 2020, capturing data from very different solar wind streams, calm and Alfvénic wind as wel…
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…
First year of energetic particle measurements in the inner heliosphere with Solar Orbiter's Energetic Particle Detector
R. F. Wimmer-Schweingruber, N. Janitzek, D. Pacheco +45
Solar Orbiter strives to unveil how the Sun controls and shapes the heliosphere and fills it with energetic particle radiation. To this end, its Energetic Particle Detector (EPD) h…
The solar-wind angular-momentum flux observed during Solar Orbiter's first orbit
Daniel Verscharen, David Stansby, Adam J. Finley +19
Aims: We present the first measurements of the solar-wind angular-momentum (AM) flux recorded by the Solar Orbiter spacecraft. Our aim is the validation of these measurements to su…
Statistical study of electron density turbulence and ion-cyclotron waves in the inner heliosphere: Solar Orbiter observations
F. Carbone, L. Sorriso-Valvo, Yu. V. Khotyaintsev +27
The recently released spacecraft potential measured by the RPW instrument on-board Solar Orbiter has been used to estimate the solar wind electron density in the inner heliosphere.…
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…
Solar wind current sheets and deHoffmann-Teller analysis: First results of DC electric field measurements by Solar Orbiter
K. Steinvall, Yu. V. Khotyaintsev, G. Cozzani +25
Solar Orbiter was launched on February 10, 2020 with the purpose of investigating solar and heliospheric physics using a payload of instruments designed for both remote and in-situ…
Kinetic Electrostatic Waves and their Association with Current Structures in the Solar Wind
D. B. Graham, Yu. V. Khotyaintsev, A. Vaivads +21
A variety of kinetic waves develop in the solar wind. The relationship between these waves and larger-scale structures, such as current sheets and ongoing turbulence remain a topic…
First-year ion-acoustic wave observations in the solar wind by the RPW/TDS instrument onboard Solar Orbiter
D. Píša, J. Souček, O. Santolík +21
Electric field measurements of the Time Domain Sampler (TDS) receiver, part of the Radio and Plasma Waves (RPW) instrument on board Solar Orbiter, often exhibit very intense broadb…
Solar Orbiter Observations of the Kelvin-Helmholtz Instability in the Solar Wind
R. Kieokaew, B. Lavraud, Y. Yang +17
The Kelvin-Helmholtz instability (KHI) is a nonlinear shear-driven instability that develops at the interface between shear flows in plasmas. KHI has been inferred in various astro…
Density Fluctuations Associated with Turbulence and Waves: First Observations by Solar Orbiter
Yu. V. Khotyaintsev, D. B. Graham, A. Vaivads +21
We use the plasma density based on measurements of the probe-to-spacecraft potential in combination with magnetic field measurements by MAG to study fields and density fluctuations…
