Global gradients for cosmic-ray protons in the heliosphere during the solar minimum of cycle 23/24
(Springer, 2016)
Global gradients for cosmic-ray (CR) protons in the heliosphere are computed with a comprehensive modulation model for the recent prolonged solar minimum of Cycle 23/24. Fortunately, the PAMELA (Payload for Antimatter ...
A global view of the modulation of cosmic ray protons in the heliosphere for the solar minimum period up to 2009
(IOP Publishing, 2016)
The heliosphere was in a state of ideal solar minimum conditions for at least three years up to the end of 2009. During this period the highest ever recorded cosmic ray spectra were observed at the Earth. Fortunately, the ...
Time dependence of the electron and positron components of the cosmic radiation measured by the PAMELA experiment between July 2006 and December 2015
(APS, 2016)
Cosmic-ray electrons and positrons are a unique probe of the propagation of cosmic rays as well as of the nature and distribution of particle sources in our Galaxy. Recent measurements of these particles are challenging ...
A remarkable recent transition in the solar dynamo
(Springer, 2016)
We summarize the major aspects of the remarkable, fairly long lasting period (∼2005 to ∼2010) of low solar activity, that we will call the Transition. It is the transitional stage between the Grand Maximum of the 20th ...
New local interstellar spectra for protons, helium and carbon derived from PAMELA and Voyager 1 observations
(Springer, 2016)
With the cosmic ray observations made by the Voyager 1 spacecraft outside the dominant modulating influence of the heliosphere, the comparison of computed galactic spectra with experimental data at lower energies is finally ...
The effects of magnetic field modifications on the solar modulation of cosmic rays with a SDE-based model
(Elsevier, 2016)
A numerical model for the solar modulation of cosmic rays, based on the solution of a set of stochastic differential equations (SDEs), is used to illustrate the effects of modifying the heliospheric magnetic field, ...
