We present results of spectral observations of two sunspots in six metal lines near Fe I 5434.5 Å, which have effective Lande factors g eff from – 0.014 to 2.14. The observations were made on July 8 and August 25, 2015, with the ATsU-5 telescope o

We report on the results of hybrid simulation of diffusive shock acceleration of ions with different charge-to-mass ratios in quasi-parallel collisionless shocks. We consider a hydrogen medium with dynamically insignificant admixtures of helium and c

An excess of 22Ne/20Ne in the isotopic composition of cosmic rays was discovered more than 40 years ago. Isotopic ratio 22Ne/20Ne measured in cosmic rays is more than five times higher than in the solar wind. It was proposed that processes in Wolf–

A nonlinear Monte Carlo model is presented in which the spectra of accelerated particles and magnetic fluctuations are calculated self-consistently, allowing for nonlinear effects and plasma instabilities in the vicinity of a strong shock wave. Diffe

While the bulk of GeV–100 TeV cosmic rays (CRs) can be accelerated at the shock of the most common supernova remnants the problem of CR acceleration to and above the PeV regime is still an open issue. We give a brief discussion of the production of

The origin of cosmic rays is one of the most important questions in modern astrophysics. Leading world observatories are engaged in their search in our Galaxy and beyond. Current observations of bright sources of hard X-rays and gamma radiation requi

We discuss a specific population of galactic PeVatrons which may be the main source of the galactic cosmic-ray (CR) component well above PeV energies. Supernovae in compact clusters of massive stars are proposed as powerful sources of CRs, neutrinos,

New observations of high-energy cosmic rays (CRs), gamma-rays and neutrinos have caused an intense debate about their origin. Detection of the most powerful astrophysical neutrinos with E > 10 15 eV by IceCube and detection of the light composition o
