Turbulence transport throughout the heliosphere [PDF]
, 2007 We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, the energy per unit mass, the ...

Plasma Dynamics in Low-Electron-Beta Environments
Frontiers in Astronomy and Space Sciences, 2021 Recent in situ measurements by the MMS and Parker Solar Probe missions bring interest to small-scale plasma dynamics (waves, turbulence, magnetic reconnection) in regions where the electron thermal energy is smaller than the magnetic one.

A MODEL OF THE HELIOSPHERE WITH JETS [PDF]
The Astrophysical Journal, 2015 An analytic model of the heliosheath (HS) between the termination shock (TS) and the heliopause (HP) is developed in the limit in which the interstellar flow and magnetic field are neglected. The heliosphere in this limit is axisymmetric and the overall structure of the HS and HP are controlled by the solar magnetic field even in the limit in which the

Heating the outer heliosphere by pickup protons [PDF]
, 2004 There is a growing body of literature that demonstrates the ability of a turbulent cascade within the solar wind to heat the thermal protons. Several sources of energy are required to accomplish the observed heating.

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

Dynamical age of solar wind turbulence in the outer heliosphere [PDF]
, 1998 In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity.

MANIFESTATIONS OF TWO BRANCHES OF SOLAR ACTIVITY IN THE HELIOSPHERE AND GCR INTENSITY
Solar-Terrestrial Physics, 2019 This paper provides insight into heliospheric processes and galactic cosmic ray (GCR) modulation occurring due to the presence of two branches of solar activity in this solar layer.

Frontiers in Astronomy and Space Sciences, 2021 In this report some properties of the electron strahl at 1 AU are examined to assess the strahl at 272 eV as an indicator of the quality of the magnetic connection of the near-Earth solar wind to the Sun.

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).
