Planar magnetic structures (PMSs), characterized by interplanetary magnetic field vectors remaining parallel to a specific plane, are commonly observed in the solar wind, especially in the sheath region of interplanetary coronal mass ejections (ICMEs). In this study, PMS events in the 2 hr regions downstream of ICME-driven shocks were investigated to reveal the relationship between PMS formation and shock environment using data collected by the Parker Solar Probe, Solar Orbiter, and Venus Express spacecraft in the inner heli ...

A Living Catalog of Parker Solar Probe IS\ensuremath\odotIS Energetic Particle Enhancements Energetic charged particles are pervasive throughout the heliosphere with contributions from solar energetic particle events, stream and corotating interaction regions, galactic cosmic rays, anomalous cosmic rays, and suprathermal ions. The Integrated Science Investigation of the Sun (IS\ensuremath\odotIS) on board the Parker Solar Probe is a suite of energetic particle detectors covering the energy range \raisebox-0.5ex\textasciitilde20 keV-200 MeV nuc$^-1$. IS\ensuremath\odotIS measures energetic particles closer to the Su ...

Parker Solar Probe Encounters the Leg of a Coronal Mass Ejection at 14 Solar Radii We use Parker Solar Probe (PSP) observations to report the first direct measurements of the particle and field environments while crossing the leg of a coronal mass ejection (CME) very close to the Sun (\raisebox-0.5ex\textasciitilde14 Rs). An analysis that combines imaging from 1 au and PSP with a CME model, predicts an encounter time and duration that correspond to an unusual, complete dropout in low-energy solar energetic ions from H-Fe, observed by the Integrated Science Investigation of the Sun (IS\ensuremath\odotIS). T ...

Clouds of Spacecraft Debris Liberated by Hypervelocity Dust Impacts on Parker Solar Probe Hypervelocity impacts on spacecraft surfaces produce a wide range of effects including transient plasma clouds, surface material ablation, and for some impacts, the liberation of spacecraft material as debris clouds. This study examines debris-producing impacts on the Parker Solar Probe spacecraft as it traverses the densest part of the zodiacal cloud: the inner heliosphere. Hypervelocity impacts by interplanetary dust grains on the spacecraft that produce debris clouds are identified and examined. Impact-generated plasma an ...

Electron Acceleration during Macroscale Magnetic Reconnection The first self-consistent simulations of electron acceleration during magnetic reconnection in a macroscale system are presented. Consistent with solar flare observations, the spectra of energetic electrons take the form of power laws that extend more than two decades in energy. The drive mechanism for these nonthermal electrons is Fermi reflection in growing and merging magnetic flux ropes. A strong guide field suppresses the production of nonthermal electrons by weakening the Fermi drive mechanism. For a weak guide field t ...

Laboratory Study of Antenna Signals Generated by Dust Impacts on Spacecraft Space missions often carry antenna instruments that are sensitive to dust impacts, however, the understanding of signal generation mechanisms remained incomplete. A signal generation model in an analytical form is presented that provides a good agreement with laboratory measurements. The model is based on the direct and induced charging of the spacecraft from the collected and escaping fraction of free charges from the impact generated plasma cloud. A set of laboratory experiments is performed using a 20:1 scaled down model ...

The NASA Parker Solar Probe and the ESA Solar Orbiter will explore the source region of the solar wind within 20 solar radii. Their unprecedented in-situ measurements are also expected to shed light on the nature of the F-corona and the existence of a halo of nanodust. Such a dust complex might play an important role in the generation of high-speed nanodust grains and the inner-source pickup ions. A brief summary of previous works on this topic is given here to be followed by a sketch on a plan to integrate MHD simulation of ...
