Recent measurements of cosmic-ray (CR) light nuclei by AMS-02 have shown that there is an unexpected component of CR lithium whose spectral index is harder than that expected from the secondary production scenario. We propose the nearby type Ia supernova following a nova eruption as the origin of lithium nuclei in the CRs. By fitting the data of CR protons, helium, and lithium fluxes provided by AMS-02 with our theoretical model we show that this scenario is consistent with the observations…

Revisiting the Spatially Dependent Propagation Model with the Latest Observations of Cosmic-Ray Nuclei
Recently AMS-02 collaboration publish their measurements of light cosmic-ray nuclei, including lithium, beryllium, boron, carbon and oxygen. All of them reveal a prominent excess above $\sim$ 200 GV,
Deciphering the Local Interstellar Spectra of Secondary Nuclei with the Galprop/Helmod Framework and a Hint for Primary Lithium in Cosmic Rays.
Local interstellar spectra (LIS) of secondary cosmic-ray (CR) nuclei, lithium, beryllium, boron, and partially secondary nitrogen, are derived in the rigidity range from 10 MV to ~200 TV using the
Origin of hardening in spectra of cosmic ray nuclei at a few hundred GeV using AMS-02 data *
Many experiments have confirmed spectral hardening at a few hundred GeV in the spectra of cosmic ray (CR) nuclei. Three different origins have been proposed: primary source acceleration, propagation,
Bayesian Analysis of the Hardening in AMS-02 Nuclei Spectra
Based on the precise nuclei data released by AMS-02, we study the spectra hardening of both the primary (proton, helium, carbon, oxygen, and the primary component of nitrogen) and the secondary
Some new hints on cosmic-ray propagation from AMS-02 nuclei spectra
In this work, we considered 2 schemes (a high-rigidity break in primary source injections and a high-rigidity break in diffusion coefficient) to reproduce the newly released AMS-02 nuclei spectra
Direct Measurement of the Cosmic-Ray Proton Spectrum from 50 GeV to 10 TeV with the Calorimetric Electron Telescope on the International Space Station.
The observed spectrum is consistent with AMS-02 but extends to nearly an order of magnitude higher energy, showing a very smooth transition of the power-law spectral index, thereby confirming the existence of spectral hardening and providing evidence of a deviation from a single power law by more than 3σ.

Origin of Spectral Hardening of Secondary Cosmic-Ray Nuclei
We discuss the acceleration and escape of secondary cosmic-ray (CR) nuclei, such as lithium, beryllium, and boron, produced by spallation of primary CR nuclei like carbon, nitrogen, and oxygen
Secondary cosmic-ray nucleus spectra disfavor particle transport in the Galaxy without reacceleration
The precise observations of Galactic cosmic ray fluxes of the secondary family, such as Li, Be, B, are expected to have significant implications on our understanding of the cosmic ray origin and


Cosmic-ray hardenings in light of AMS-02 data
Recent precise observations of cosmic rays (CRs) by AMS-02 experiment clearly show (1) harder spectra of helium and carbon compared to protons by $\propto R^{0.08}$, and (2) concave breaks in proton
Cosmic-ray helium hardening
Recent observations by the ATIC-2, CREAM and PAMELA experiments suggest that the spectrum of cosmic- ray (CR) helium is harder than that of CR protons below the knee energy and all CR spectra become
Signatures of a Two Million Year Old Supernova in the Spectra of Cosmic Ray Protons, Antiprotons, and Positrons.
The age of the supernova suggests that the local cosmic ray injection was produced by the same supernova that has deposited ^{60}Fe isotopes in the deep ocean crust.

We present a quantitative model of Galactic cosmic-ray (GCR) origin and acceleration, wherein a mixture of interstellar and/or circumstellar gas and dust is accelerated by a supernova remnant blast
Indications for a High-Rigidity Break in the Cosmic-Ray Diffusion Coefficient.
Using cosmic-ray boron to carbon ratio (B/C) data recently released by the Ams-02 experiment, indications are found in favor of a diffusive propagation origin for the broken power-law spectra found in protons and helium nuclei.

Galactic Cosmic Rays from Supernova Remnants. I. A Cosmic-Ray Composition Controlled by Volatility and Mass-to-Charge Ratio
We show that the Galactic cosmic-ray source (GCRS) composition is best described in terms of (1) a general enhancement of the refractory elements relative to the volatile ones, and (2) among the
Nearby supernova remnants and the cosmic ray spectral hardening at high energies
Recent measurements of cosmic ray spectra of several individual nuclear species by the CREAM, TRACER and ATIC experiments indicate a change in the spectral index of the power laws at TeV energies.
Detection of the Characteristic Pion-Decay Signature in Supernova Remnants
The characteristic pion-decay feature is detected in the gamma-ray spectra of two SNRs, IC 443 and W44, with the Fermi Large Area Telescope, providing direct evidence that cosmic-ray protons are accelerated in SNRs.
PAMELA Measurements of Cosmic-Ray Proton and Helium Spectra
PAMELA data challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy and find that the spectral shapes of these two species are different and cannot be described well by a single power law.
