Modeling drift along the heliospheric wavy neutral sheet
(IOP Publishing, 2012)
Drift along the wavy heliospheric neutral sheet is believed to play an important role in cosmic-ray modulation and can explain the peaked versus flat intensity profiles during consecutive solar magnetic epochs. Modulation ...
Modelling the effects of scattering parameters on particle-drift in the solar modulation of galactic cosmic rays
(Elsevier, 2015)
It is well known that particle drift motions are suppressed by diffusive scattering as established by direct numerical simulations. The effect of constant scattering on the drift velocities of charged particles has always ...
A numerical study of cosmic proton modulation using AMS-02 observations
(IOP Publishing, 2019)
Since 2011 May, the Alpha Magnetic Spectrometer (AMS-02) on board the International Space Station has provided monthly cosmic proton fluxes for various low-rigidity levels (P<50 GV). These precise measurements, in terms ...
Sensitivity of cosmic-ray proton spectra to the low-wavenumber behavior of the 2D turbulence power spectrum
(IOP Publishing, 2015)
In this study, a novel ab initio cosmic ray (CR) modulation code that solves a set of stochastic transport equations
equivalent to the Parker transport equation, and that uses output from a turbulence transport code as ...
The effect of a dynamic inner heliosheath thickness on cosmic-ray modulation
(IOP Publishing, 2015)
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied over different polarity cycles by
computing 2.5 GV proton intensities using a two-dimensional, time-dependent modulationmodel. By ...
Cosmic-ray positrons from millisecond pulsars
(IOP Publishing, 2015)
Observations by the Fermi Large Area Telescope of γ-ray millisecond pulsar (MSP) light curves imply copious pair
production in their magnetospheres, and not exclusively in those of younger pulsars. Such pair cascades may ...
Modelling anomalous cosmic ray oxygen in the heliosheath
(EDP Sciences, 2010)
This paper discusses a numerical modulation model to describe anomalous cosmic ray acceleration and transport in the heliosheath, the portion of the heliosphere between the termination shock and the heliopause. The model ...
Long-term neutron monitor observations and the 2009 cosmic ray maximum
(American Geophysical Union, 2010)
The solar minimum of 2009 was characterized by a prolonged increase toward the maximum cosmic ray intensity, which was higher than it was during the maxima of 22 and 44 years ago. In the previous two so-called qA <0 (solar ...
The role of radial perpendicular diffusion and latitude dependent acceleration along the solar
(Elsevier, 2008)
A numerical model, based on Parker’s transport equation, describing the modulation of anomalous cosmic rays and containing diffusive shock acceleration is applied. The role of radial perpendicular diffusion at the solar ...
Time dependence of the proton flux measured by Pamela during the 2006 July-2009 December solar minimum
(IOP Science, 2013)
The energy spectra of galactic cosmic rays carry fundamental information regarding their origin and propagation. These spectra, when measured near Earth, are significantly affected by the solar magnetic field. A comprehensive ...
