Parker Solar Probe Observations of Compound Reconnection Exhaust Boundaries and Mirror-mode Structures in the near-Sun Heliospheric Current Sheet

Weijie Sun, Tai Phan, Jia Huang, Yi-Hsin Liu et autres

Abstract Magnetic reconnection is a fundamental physical process that can drive rapid conversion of magnetic energy into plasma bulk flows, thermal heating, and particle acceleration in space and astrophysical plasmas. Classical reconnection theory predicts that the Alfvénic reconnection exhausts are bounded by …

The Temperature Anisotropy and Helium Abundance Features of Alfvénic Slow Solar Wind Observed by Parker Solar Probe, Helios, and Wind Missions

Jia Huang, D. E. Larson, Tamar Ervin, Mingzhe Liu et autres

Abstract Slow solar wind is typically characterized as having low Alfvénicity, but the occasional occurrence of highly Alfvénic slow solar wind (HASSW) raises questions about its source regions and evolution. In this work, we conduct a statistical analysis of temperature anisotropy and …

Quasithermal Noise in Magnetized Plasma: Theory and Simulations

Xianming Zheng, Mihailo M. Martinović, K. G. Klein, Viviane Pierrard et autres

Abstract Quasithermal noise (QTN) spectroscopy has been extensively used as an accurate tool to measure electron density and temperature in unmagnetized space plasmas. The observed spectrum depends on both antenna geometry and plasma kinetic properties. When considering the QTN signal of a …

Impulsive Solar Flares in the Parker Solar Probe Era. I. Low-energy Electron, Proton, and Alpha Beams

S. Al‐Nussirat, D. E. Larson, R. Livi, P. L. Whittlesey et autres

Abstract Multiple instruments on board the Parker Solar Probe spacecraft have detected signatures of impulsive electron and ion beam events over the course of the first 20 encounters. The energy spectra of these events are characterized by a peak originating in the …

In Situ Measurements of Dark Photon Dark Matter Using Parker Solar Probe: Going beyond the Radio Window

Haipeng An, Shuailiang Ge, Jia Liu, Mingzhe Liu

Dark photon dark matter (DPDM) emerges as a compelling candidate for ultralight bosonic dark matter, detectable through resonant conversion into photons within a plasma environment. This Letter employs in situ measurements from the Parker Solar Probe (PSP), the first spacecraft to venture …

Room‐Temperature Organic Spintronic Devices with Wide Range Magnetocurrent Tuning and Multifunctionality via Electro‐Optical Compensation Strategy

Ke Meng, Min Li, Lidan Guo, Rui Zhang et autres

In spintronics, devices exhibiting large, widely tunable magnetocurrent (MC) values at room temperature are particularly appealing due to their potential in advanced sensing, data storage, and multifunctional technologies. Organic semiconductors (OSCs), with their rich and unique spin-dependent and (opto-)electronic properties, hold significant …

Radial Evolution of Non-Maxwellian Electron Populations Derived from Quasi-thermal Noise Spectroscopy: Parker Solar Probe Observations

Xianming Zheng, Mihailo M. Martinović, Viviane Pierrard, K. G. Klein et autres

Abstract Understanding the transport of energy within space plasmas, particularly in the solar wind, remains a complex challenge. Accurate measurement of electron temperatures and their nonthermal characteristics is crucial for comprehending energy transport properties in plasmas. Quasi-thermal-noise (QTN) spectroscopy has emerged as …

Establishment and Application of an Interplanetary Disturbance Index Based on the Solar Wind–Magnetosphere Energy Coupling Function and the Spectral Whitening Method

Xiaowei Zhao, Jingsong Wang, Ming‐Xian Zhao, Ying D. Liu et autres

Abstract We develop a preliminary interplanetary disturbance index (J s W ) by applying the spectral whitening method to an energy coupling function with solar wind measurements during the years 1998–2014 as the input, which can be used as an indicator of …
