TL;DR
This paper investigates the origin of cosmic rays, showing that astrophysical objects with strong magnetic fields produce a power-law spectrum of accelerated particles with an exponent of -2.5, based on geometrical considerations.
Contribution
It introduces a geometrical model explaining the spectral index of cosmic rays from magnetic astrophysical sources, independent of particle type.
Findings
Charged particle spectra follow a power law with exponent -2.5.
The spectral index is derived purely from geometrical considerations.
The result is independent of particle species.
Abstract
Study of astrophysical objects with strong dipolar magnetic fields show that the spectrum of the accelerated charged particles leaving the sources has a power law form with exponent -2.5, where the exponent is calculated on purely geometrical bases and is independent on the particle species.
