Abstract We have measured the isotopic abundances of neon and a number of other species in the galactic cosmic rays (GCRs) using the Cosmic Ray Isotope Spectrometer (CRIS) aboard the ACE spacecraft. Our data are compared to recent results from two-component (Wolf–Rayet material plus solar-like mixtures) Wolf–Rayet (WR) models. The three largest deviations of galactic cosmic ray isotope ratios from solar-system ratios predicted by these models, 12C/16O, 22Ne/20Ne, and 58Fe/56Fe, are very close… 

Impact of Low-Energy Cosmic Rays on Star Formation

In recent years, exciting developments have taken place in the identification of the role of cosmic rays in star-forming environments. Observations from radio to infrared wavelengths and theoretical

Elemental Composition at the Cosmic-Ray Source Derived from the ACE-CRIS Instrument. I. 6C to 28Ni

We report new elemental source abundances from 6C to 28Ni for galactic cosmic rays, using observations from the Cosmic Ray Isotope Spectrometer (CRIS) on board the NASA Advanced Composition Explorer

Inference of the Local Interstellar Spectra of Cosmic-Ray Nuclei Z ≤ 28 with the GalProp–HelMod Framework

A fraction of HEAO-3-C2 data can be used together with Voyager 1 and ACE-CRIS data to make predictions for the local interstellar spectra (LIS) of nuclei that are not yet released by AMS-02, and the GalProp-HelMod framework is used in deriving the LIS of CR p ¯, e -, and nuclei 1H-8O.

Are Anomalous Cosmic Rays the Main Contribution to the Low-Energy Galactic Cosmic Ray Spectrum?

While the high-energy part of the Galactic cosmic ray spectrum is well observed, its nature at energies below about 1 GeV nucleon-1 is still not known well. Recent in situ measurements made with the


The balloon-borne Cosmic Ray Energetics And Mass experiment launched five times from Antarctica has achieved a cumulative flight duration of about 156 days above 99.5% of the atmosphere. The

An Overview of the Origin of Galactic Cosmic Rays as Inferred from Observations of Heavy Ion Composition and Spectra

Abstract The galactic cosmic rays arriving near Earth, which include both stable and long-lived nuclides from throughout the periodic table, consist of a mix of stellar nucleosynthesis products

The Nine Lives of Cosmic Rays in Galaxies

© 2015 by Annual Reviews. Cosmic-ray astrophysics has advanced rapidly in recent years, and its impact on other astronomical disciplines has broadened. Many new experiments measuring these particles,



Wolf-Rayet stars, OB associations, and the origin of galactic cosmic rays

Cosmic-Ray Neon, Wolf-Rayet Stars, and the Superbubble Origin of Galactic Cosmic Rays

We report the abundances of neon isotopes in the Galactic cosmic rays (GCRs) using data from the Cosmic Ray Isotope Spectrometer (CRIS) aboard the Advanced Composition Explorer (ACE). These

Isotopic anomalies in cosmic rays and the metallicity gradient in the Galaxy

We suggest that the so called isotopic anomalies present in galactic cosmic ray sources (GCRS) result from the fact that the local galactic medium is compared to accelerated matter originating mainly

Contribution of Wolf-Rayet stars to the synthesis of 26Al I. The γ-ray connection

New 26Al yield predictions are derived from Wolf-Rayet (WR) model stars that are able to account better than previous ones for many important observed characteristics (like luminosities, surface

Stellar evolution with rotation X: Wolf-Rayet star populations at solar metallicity

We examine the properties of Wolf-Rayet (WR) stars predicted by models of rotating stars taking account of the new mass loss rates for O-type stars and WR stars (Vink et al. 2000. 2001; Nugis &

GCR neon isotopic abundances: Comparison with wolf-rayet star models and meteoritic abundances

Measurements of the neon isotopic abundances from the ACE-CRIS experiment are presented. These abundances have been obtained in seven energy intervals over the energy range of ~80≤E≤280 MeV/nucleon.

Isotopic anomalies in the galactic cosmic-ray source

Observations of the isotopic compositions of oxygen, neon and magnesium nuclei in galactic cosmic rays are presented and discussed in terms of nucleosynthesis at the galactic cosmic ray source. The

The formation of the solar system inside an OB association is examined with particular attenuation to the elemental abundances which would have been ejected by the association's first few supernovae.

Galactic Metallicity Gradients Derived from a Sample of OB Stars

The distribution of stellar abundances along the Galactic disk is an important constraint for models of chemical evolution and Galaxy formation. In this study we derive radial gradients of C, N, O,

We have considered the effects of both the spatial and temporal clustering of OB stars and their subsequent core-collapse supernovae on their generation of superbubbles and their resultant role as
