Particle Radiation Environment in the Heliosphere: Status, limitations and recommendations
Jingnan Guo, Bingbing Wang, Kathryn Whitman +14
Space weather is a multidisciplinary research area connecting scientists from across heliophysics domains seeking a coherent understanding of our space environment that can also se…
Coronal Heating Rate in the Slow Solar Wind
Daniele Telloni, Marco Romoli, Marco Velli +59
This Letter reports the first observational estimate of the heating rate in the slowly expanding solar corona. The analysis exploits the simultaneous remote and local observations…
Phase Coherence of Solar Wind Turbulence from the Sun to Earth
Masaru Nakanotani, Lingling Zhao, Gary P. Zank
The transport of energetic particles in response to solar wind turbulence is important for space weather. To understand charged particle transport, it is usually assumed that the p…
Does Turbulence along the Coronal Current Sheet Drive Ion Cyclotron Waves?
Daniele Telloni, Gary P. Zank, Laxman Adhikari +32
Evidence for the presence of ion cyclotron waves, driven by turbulence, at the boundaries of the current sheet is reported in this paper. By exploiting the full potential of the jo…
The Structure and Origin of Switchbacks: Parker Solar Probe Observations
Jia Huang, J. C. Kasper, L. A. Fisk +25
Switchbacks are rapid magnetic field reversals that last from seconds to hours. Current Parker Solar Probe (PSP) observations pose many open questions in regard to the nature of sw…
Turbulence in the outer heliosphere
Federico Fraternale, Laxman Adhikari, Horst Fichtner +9
The solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their interaction is governed by complex physical processes and creates heliospheric regions with sign…
First report of a solar energetic particle event observed by China's Tianwen-1 mission in transit to Mars
Shuai Fu, Zheyi Ding, Yongjie Zhang +15
Solar energetic particles (SEPs) associated with flares and/or coronal mass ejection (CME)-driven shocks can impose acute radiation hazards to space explorations. To measure energe…
Modeling of Joint Parker Solar Probe - Metis/Solar Orbiter Observations
Laxman Adhikari, Gary P. Zank, Daniele Telloni +1
We present a first theoretical modeling of joint Parker Solar Probe (PSP) - Metis/Solar Orbiter (SolO) quadrature observations Telloni et al 2022c. The combined observations descri…
Observation of Magnetic Switchback in the Solar Corona
Daniele Telloni, Gary P. Zank, Marco Stangalini +49
Switchbacks are sudden, large radial deflections of the solar wind magnetic field, widely revealed in interplanetary space by the Parker Solar Probe. The switchbacks' formation mec…
Particle acceleration in an MHD-scale system of multiple current sheets
M. Nakanotani, G. P. Zank, L. -L. Zhao
We investigate particle acceleration in an MHD-scale system of multiple current sheets by performing 2D and 3D MHD simulations combined with a test particle simulation. The system…
Comparison of Anomalous and Galactic Cosmic Ray Oxygen at 1 au during 1997-2020
Shuai Fu, Lingling Zhao, Xiaoping Zhang +2
Using quiet-time measurements of element oxygen within the energy range 7.3--237.9 MeV nuc from the ACE spacecraft at 1 au, we compare the energy spectra and intensities of…
Configuration of a Magnetic Cloud from Solar Orbiter and Wind Spacecraft In-situ Measurements
Qiang Hu, Wen He, Lingling Zhao +1
Coronal mass ejections (CMEs) represent one type of the major eruption from the Sun. Their interplanetary counterparts, the interplanetary CMEs (ICMEs), are the direct manifestatio…
Small-scale Magnetic Flux Ropes with Field-aligned Flows via the PSP In-situ Observations
Yu Chen, Qiang Hu, Lingling Zhao +2
Magnetic flux rope, formed by the helical magnetic field lines, can sometimes remain its shape while carrying significant plasma flow that is aligned with the local magnetic field.…
Variations of the Galactic Cosmic Rays in the Recent Solar Cycles
Shuai Fu, Xiaoping Zhang, Lingling Zhao +1
In this paper, we study the galactic cosmic ray (GCR) variations over the solar cycles 23 and 24, with measurements from the NASA's ACE/CRIS instrument and the ground-based neutron…
Small-scale Magnetic Flux Ropes in the First two Parker Solar Probe Encounters
Yu Chen, Qiang Hu, Lingling Zhao +15
Small-scale magnetic flux ropes (SFRs) are a type of structures in the solar wind that possess helical magnetic field lines. In a recent report (Chen & Hu 2020), we presented the r…
An ACE/CRIS-observation-based Galactic Cosmic Rays heavy nuclei spectra model II
Shuai Fu, LingLing Zhao, Gary P. Zank +2
An observation-based Galactic Cosmic Ray (GCR) spectral model for heavy nuclei is developed. Zhao and Qin (J. Geophys. Res. Space Phys.118, 1837(2013)) proposed an empirical elemen…
