Viewing Global Changes in the Heliosheath with IMAP’s Energetic Neutral Atom Imagers

The Astrophysical Journal
We present a simulation analysis of NASA’s upcoming Interstellar Mapping and Acceleration Probe (IMAP) energetic neutral atom (ENA) instrument capabilities in viewing “global” changes in the heliosheath (HS) plasma, and the resulting ENA flux changes ...

Reconstructing the long-term cosmic ray intensity: linear relations do not work [PDF]

Annales Geophysicae, 2003
It was recently suggested (Lockwood, 2001) that the cosmic ray intensity in the neutron monitor energy range is linearly related to the coronal source flux, and can be reconstructed for the last 130 years using the long-term coronal flux estimated ...

Distance to the Solar Wind Termination Shock and the Source Flux of Anomalous Cosmic Rays During 1986-1988 [PDF]

, 1994
We use observations of the intensity of anomalous cosmic ray helium and oxygen in the outer heliosphere near the last solar minimum period, in conjunction with solar observations of the tilt of the neutral current sheet, to estimate that the solar wind ...

The gradient of galactic cosmic rays at the solar-wind termination shock

The Astrophysical Journal, 1993
We report on a study of the expected spatial variation of the galactic cosmic-ray intensity in the outer heliosphere, in the vicinity of the solar-wind termination shock. Model simulations which contain all of the transport effects, including drifts, predict that the radial gradients change abruptly at the shock, and that the nature of the effect ...

Recent Developments in Energy Storage and Conversion Applications of Multifunctional Vanadium Carbides

Advanced Materials Technologies, EarlyView.
This review systematically explains the synthesis, properties, and energy storage and conversion applications of vanadium carbides. We introduce the structural and the synthetic strategies and reviewed recent developments in the material synthesis processes. The emerging applications of vanadium carbides in energy storage and conversion are highlighted.

Turbulence, Waves, and Taylor’s Hypothesis for Heliosheath Observations

The Astrophysical Journal
Magnetic field fluctuations measured in the heliosheath by the Voyager spacecraft are often characterized as compressible, as indicated by a strong fluctuating component parallel to the mean magnetic field.

Interfacial Engineering by Metallic Ions and Organic Ammonium Ligand Passivation for Perovskite Solar Cells

Advanced Science, EarlyView.
A synergistic approach using phenethylammonium iodide (PEAI) and antimony iodide (SbI3) enhances the operational stabilities of perovskite solar cells by providing p‐type doping effect, suitable band energy alignment, reduced defect density, and minimized surface ion vacancies in the perovskite films.

Termination Shock Particle Streaming Upstream at New Horizons

The Astrophysical Journal Letters
A couple years before Voyager 1 and Voyager 2 (V2) crossed the termination shock (TS), instruments on board both spacecraft observed high intensities of accelerated termination shock particles (TSPs) beaming in opposite directions.

PRESSURE ANISOTROPIES MAPPED THROUGH THE SOLAR WIND TERMINATION SHOCK

The Astrophysical Journal, 2009
With the observations made at the more recent crossings of the Voyager space probes over the solar wind termination shock, up-to-date knowledge of the physics at astrophysical shocks has been deeply challenged in many respects. In this paper, we mainly address the associated facts that the ion plasma downstream of the shock appears to be ...

Solar Wind Speed and Temperature Outside 10 AU and the Termination Shock [PDF]

The Astrophysical Journal, 2003
In this paper we first present a series of pickup proton solar wind solutions following the fluid motion in the upwind direction to show that the wind speed V and temperature T, at a given r outside 10 AU, are primarily functions of the 1 AU wind speed V0.
