Contributions from nearby pulsars to the local cosmic ray electron spectrum
(Elsevier, 2008)PSR J0437-4715 is one of the closest millisecond pulsars (MSPs) to Earth, lying at a distance of ∼140 pc. This pulsar has a characteristic age of 4.9 Gyr and a relatively low spindown power of ∼1034 ergs/s. During its ... -
Long-term variation in cosmic-ray modulation
(North-West University (South Africa), 2017)The transport of cosmic rays inside the heliosphere can be described b the Parker equation (Parker, 1965). Since there are no full analytica solutions to the Parker equation, two first-order approximate solutions o the ... -
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 ...
