A Tilt Model for Anomalous Cosmic Rays and the Location of the Solar Wind Termination Shock [PDF]

open access: yes, 1999
We use the observed relationship of the radial gradient of anomalous cosmic rays (ACRs), as measured in the outer heliosphere with instruments on the Voyager and Pioneer spacecraft, and the tilt of the heliospheric neutral current sheet to develop a ...

The Role of Pickup Ions in the Interaction of the Solar Wind with the Local Interstellar Medium. II. Effects of Solar Cycle

open access: yesThe Astrophysical Journal
We investigate the role of pickup ions (PUIs) in the interaction of a periodically varying solar wind (SW) with the local interstellar medium (LISM).

Zinc Sulfide Enabling Remarkable Surface Passivation of Crystalline Silicon

open access: yesAdvanced Energy Materials, EarlyView.
Polycrystalline ZnS films capped by Al2O3 provide outstanding surface passivation performance. The excellent lattice agreement between c‐Si and ZnS combined with a hydrogenation step result in extremely low interface state density (≈ 1×1010 cm−2 eV−1) and recombination current pre‐factor (1.0 fA/cm2), revealing a new passivation strategy for ...

2D Kelvin–Helmholtz Instability with Anisotropic Pressure

open access: yesThe Astrophysical Journal
The Kelvin–Helmholtz (KH) instability occurs in multiple heliospheric (solar-wind stream interfaces, planetary magnetospheres, cometary tails, heliopause flanks) and interstellar (protoplanetary disks, relativistic jets, neutron star accretion disks ...

Shocks, Compressible Perturbations, and Intermittency in the Very Local Interstellar Medium: Voyager 1 and 2 Observations and Numerical Modeling

open access: yesThe Astrophysical Journal
The Voyager spacecraft (V1 and V2) provide unique in situ measurements of perturbations propagating beyond the heliopause through the very local interstellar medium (VLISM), including the shocks and pressure fronts whose origin is debated. In particular,

A “Valley” in Heliospheric Energetic Particle Intensities and Implications for a New Horizons Encounter with the Solar Wind Termination Shock

open access: yesThe Astrophysical Journal
We analyze ∼40–200 keV energetic particle observations from the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) on board the New Horizons (NH) spacecraft from 2007 to 2024 and compare them with similar measurements from the Low ...

Embedding Chemistry and Pharmacy Into Sustainability

open access: yesAngewandte Chemie International Edition, EarlyView.
Chemistry and pharmacy provide products and processes that are indispensable for our high living standard. To understand their relationship with sustainability is important to allow them to contribute to sustainability in a sustainable manner. An integrated overview of green, circular, and sustainable chemistry and pharmacy is given and how they have t
