In Situ Observations of Interstellar Plasma With Voyager 1 (Invited)

TL;DR: Electron densities detected by Voyager 1 show that the spacecraft is in the interstellar plasma, and other observations provide strong evidence that Voyager 1 has crossed the heliopause into the nearby interstellar plasma.

Observation of Complex Time Structures in the Cosmic-Ray Electron and Positron Fluxes with the Alpha Magnetic Spectrometer on the International Space Station.

M. Aguilar, +251 more
TL;DR: High-statistics, precision measurements of the detailed time and energy dependence of the primary cosmic-ray electron flux and positron flux over 79 Bartels rotations from May 2011 to May 2017 in the energy range from 1 to 50 GeV show that the ratio exhibits a smooth transition over 830±30 days from one value to another.

New Very Local Interstellar Spectra for Electrons, Positrons, Protons, and Light Cosmic Ray Nuclei

TL;DR: In this article, the authors used the most comprehensive galactic propagation model (GALPROP) along with a sophisticated solar modulation model to compare the computed spectra with the observed PAMELA spectra over a wide energy range.

The passage of energetic charged particles through interplanetary space

TL;DR: In this article, a general expression for the particle diffusion coefficient kij, including both scattering in magnetic irregularities and systematic pressure drifts, was derived from the condition that energetic solar particles in interplanetary space random walk in the irregularities in the large-scale inter-planetary magnetic field, and the observed fields show that the diffusion coefficient is of the order of 1021-1022 cm2/sec.

First result from the Alpha Magnetic Spectrometer on the International Space Station: precision measurement of the positron fraction in primary cosmic rays of 0.5-350 GeV.

M. Aguilar, +347 more
TL;DR: The very accurate data show that the positron fraction is steadily increasing from 10 to ∼ 250 GeV, but, from 20 to 250 GeV, the slope decreases by an order of magnitude, showing the existence of new physical phenomena.
