, 2014 Context. Since 1996, during periods of low solar activity, the HSTOF instrument onboard the SOHO satellite has been measuring weak fluxes of He atoms of 28-58 keV/n (helium energetic neutral atoms - He ENA).

Evolving outer heliosphere: Large-scale stability and time variations observed by the Interstellar Boundary Explorer [PDF]
, 2010 The first all-sky maps of Energetic Neutral Atoms (ENAs) from the Interstellar Boundary Explorer (IBEX) exhibited smoothly varying, globally distributed flux and a narrow ribbon of enhanced ENA emissions.

Proton Cyclotron Waves and Pickup Ion Ring Distribution Instabilities Upstream of Mars
Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.Abstract Proton cyclotron waves (PCWs) upstream of Mars are thought to be associated with the instabilities of pickup ions. The instabilities of pickup ions of ring distributions have larger maximum growth rates compared with beam distributions.

Evidence for an interstellar dust filament in the outer heliosheath
, 2015 A recently discovered filament of polarized starlight that traces a coherent magnetic field is shown to have several properties that are consistent with an origin in the outer heliosheath of the heliosphere: (1) The magnetic field that provides the best ...

Termination shock particle spectral features [PDF]
, 2006 Spectral features of energetic H ions accelerated at the termination shock may be evidence of two components. At low energies the energy spectrum is ~E^(–1.55), with break at ~0.4 MeV to E^(–2.2).

Mapping the magnetic mayhem in the heliosheath [PDF]
Eos, Transactions American Geophysical Union, 2011 When Voyager 1 passed into the heliosheath in 2004, it became the first human‐made object to explore the remote edge of the Sun's magnetic influence. The heliosheath, between 1.5 and 15 billion kilometers thick and starting roughly 14 billion kilometers from the Sun, is where the outgoing flows of solar wind start to be pushed back by interstellar ...

A model for the nose region of the heliosheath
Journal of Physics: Conference Series, 2015 The Voyager 1 spacecraft is currently in the vicinity of the heliopause, which separates the heliosphere from the local interstellar medium. There has been a precipitous decrease in particles accelerated in the heliosphere, and a substantial increase in galactic cosmic rays (GCRs), suggesting easy escape of the former across the heliopause, and entry ...

SCALING OF THE GROWTH RATE OF MAGNETIC ISLANDS IN THE HELIOSHEATH [PDF]
The Astrophysical Journal, 2012 Current sheets thinner than the ion inertial length are unstable to the tearing instability and will develop magnetic islands that grow due to magnetic reconnection. We investigate whether the growth of magnetic islands in a current sheet can continue indefinitely, or in the case of the heliosheath until reaching a neighboring current sheet, and at ...
