Transient heliosheath modulation [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Voyager 1 has explored the solar wind-interstellar medium interaction region between the terminal shock and heliopause following the intensity distribution of galactic cosmic ray protons above 200 MeV energy. Before this component reached the galactic level at 121.7 AU, 4 episodes of rapid intensity change occured similar to the Forbush Decreases found

Frontiers in Astronomy and Space Sciences, 2023 The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...

On the Vitality, or Lack Thereof, in Heliospheric and Coronal Physics
Perspectives of Earth and Space Scientists, Volume 4, Issue 1, December 2023., 2023 Abstract Heliospheric physics is the study of all phenomena in the solar wind, which carves out the heliosphere from the local interstellar medium. Coronal physics is the study of all phenomena in the solar corona, which creates the supersonic wind and all disturbances and variations contained therein.

On the Temperatures of Planetary Magnetosheaths at the Subsolar Points
Journal of Geophysical Research: Space Physics, Volume 127, Issue 11, November 2022., 2022 Abstract This research explores the relationship between the temperatures of the solar corona and planetary magnetosheaths. Based on the second law of thermodynamics, the maximum temperature of the planetary magnetosheaths cannot exceed that of the solar corona.

Relating Energetic Ion Spectra to Energetic Neutral Atoms
The Astrophysical Journal, 2023 Heliospheric energetic neutral atoms (ENAs) originate from energetic ions that are neutralized by charge exchange with neutral atoms in the heliosheath and very local interstellar medium (VLISM).

Effects of the solar wind termination shock and heliosheath on theheliospheric modulation of galactic and anomalous Helium [PDF]
Annales Geophysicae, 2004 The interest in the role of the solar wind termination shock and heliosheath in cosmic ray modulation studies has increased significantly as the Voyager 1 and 2 spacecraft approach the estimated position of the solar wind termination shock.

Unexpected sites of efficient stochastic acceleration in the inner heliosheath [PDF]
Annales Geophysicae, 2007 Up until the recent past, it was generally believed that the solar wind termination shock (TS) is the favourite site to accelerate ions from the keV- to the MeV- energy levels by means of Fermi-1 processes.

The Role of Electrons and Helium Atoms in Global Modeling of the Heliosphere
The Astrophysical Journal, 2023 We present a new three-dimensional, MHD-plasma/kinetic-neutrals model of the solar wind (SW) interaction with the local interstellar medium (LISM), which self-consistently includes neutral hydrogen and helium atoms.
