Time dependence of the flux of helium nuclei in cosmic rays measured by the PAMELA experiment between July 2006 and December 2009
N. Marcelli, M. Boezio, A. Lenni +53
Precise time-dependent measurements of the Z = 2 component in the cosmic radiation provide crucial information about the propagation of charged particles through the heliosphere. T…
Solar modulation of cosmic ray positrons in a very quiet heliosphere
M. S. Potgieter, E. E. Vos, D. Bisschoff +4
Since the beginning of the space exploration era, solar activity was observed at its lowest level during 2006 to 2009. During this period, the PAMELA space experiment observed spec…
New evidence for charge-sign dependent modulation during the solar minimum of 2006 to 2009
V. Di Felice, R. Munini, E. E. Vos +1
The PAMELA space experiment, in orbit since 2006, has measured cosmic rays through the most recent A < 0 solar minimum activity period. During this entire time, galactic electrons…
The effect of magnetic field modifications on the modulation of cosmic rays in the heliosphere
J. L. Raath, M. S. Potgieter, R. D. Strauss +1
A numerical model for the solar modulation of cosmic rays, based on the solution of a set of stochastic differential equations, is used to illustrate the effects of modifying the h…
The Discrepancy in Modelling of Galactic Cosmic Ray Primaries and Secondaries
D. Bisschoff, I. Büsching, M. S. Potgieter
Given that the bulk of the galactic cosmic rays (CRs) originates from transient point-like sources, such as supernova remnants, the flux of the CR primary component measured at Ear…
A Very Local Interstellar Spectrum for Galactic Electrons
M. S. Potgieter, E. E. Vos, R. R. Nndanganeni +2
We present a new local interstellar spectrum for cosmic ray electrons over an energy range from 1 MeV to 70 GeV. Below (0.8 plus minus 0.2) GeV it has a power law form, E^-(1.55 pl…
Time dependence of the proton flux measured by PAMELA during the July 2006 - December 2009 solar minimum
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +61
The energy spectra of galactic cosmic rays carry fundamental information regarding their origin and propagation. These spectra, when measured near Earth, are significantly affected…
A Cosmic Ray Positron Anisotropy due to Two Middle-Aged, Nearby Pulsars?
I. Buesching, O. C. de Jager, M. S. Potgieter +1
Geminga and B0656+14 are the closest pulsars with characteristic ages in the ran ge of 100 kyr to 1 Myr. They both have spindown powers of the order 3e34 erg/s at present. The wind…
