Kinetic Scale Slow Solar Wind Turbulence in the Inner Heliosphere: Coexistence of Kinetic Alfvén Waves and Alfvén Ion Cyclotron Waves [PDF]
Astrophysical Journal, 2020 The nature of the plasma wave modes around the ion kinetic scales in highly Alfvénic slow solar wind turbulence is investigated using data from the NASA’s Parker Solar Probe taken in the inner heliosphere, at 0.18 au from the Sun.

The long-term variability of cosmic ray protons in the heliosphere: A modeling approach
Journal of Advanced Research, 2013 Galactic cosmic rays are charged particles created in our galaxy and beyond. They propagate through interstellar space to eventually reach the heliosphere and Earth. Their transport in the heliosphere is subjected to four modulation processes: diffusion,

Solar energetic particle time series analysis with Python
Frontiers in Astronomy and Space Sciences, 2022 Solar Energetic Particles (SEPs) are charged particles accelerated within the solar atmosphere or the interplanetary space by explosive phenomena such as solar flares or Coronal Mass Ejections (CMEs). Once injected into the interplanetary space, they can

Solar wind stream interaction regions throughout the heliosphere
Living Reviews in Solar Physics, 2018 This paper focuses on the interactions between the fast solar wind from coronal holes and the intervening slower solar wind, leading to the creation of stream interaction regions that corotate with the Sun and may persist for many solar rotations. Stream

Connection of Turbulence with Polytropic Index in the Solar Wind Proton Plasma
Entropy, 2019 This paper improves our understanding of the interplay of the proton plasma turbulent heating sources of the expanding solar wind in the heliosphere. Evidence is shown of the connections between the polytropic index, the rate of the heat absorbed by the ...

Expansion of magnetic clouds in the outer heliosphere [PDF]
, 2012 A large amount of magnetized plasma is frequently ejected from the Sun as coronal mass ejections (CMEs). Some of these ejections are detected in the solar wind as magnetic clouds (MCs) that have flux rope signatures.

Improving Predictions of High‐Latitude Coronal Mass Ejections Throughout the Heliosphere
Space Weather, 2020 Predictions of the impact of coronal mass ejections (CMEs) in the heliosphere mostly rely on cone CME models, whose performances are optimized for locations in the ecliptic plane and at 1 AU (e.g., at Earth).
