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 ...
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 ...
An AB initio model for the modulation of galactic cosmic-ray electrons
(IOP Publishing, 2013)
The modulation of galactic cosmic-ray electrons is studied using an ab initio three-dimensional steady state cosmicraymodulation
code in which the effects of turbulence on both the diffusion and drift of these cosmic-rays ...
An AB initio model for cosmic-ray modulation
(IOP Publishing, 2013)
A proper understanding of the effects of turbulence on the diffusion and drift of cosmic rays (CRs) is of vital
importance for a better understanding of CR modulation in the heliosphere. This study presents an ab initio ...
Cosmic ray modulation with a Fisk-type heliospheric magnetic field and a latitude-dependent solar wind speed
(Elsevier, 2009)
The effect of a latitude-dependent solar wind speed on a Fisk heliospheric magnetic field [Fisk, L. A. Motion of the footpoints of heliospheric magnetic field lines at the Sun: implications for recurrent energetic particle ...
Three-dimensional wavy heliospheric current sheet drifts
(IOP publishing, 2012)
We present an analytic method to determine the directions of the three-dimensional (3D) heliospheric current sheet (HCS) drift for any tilt angle based on Parker's heliospheric magnetic field and compare it with published ...
A Fisk-Parker hybrid heliospheric magnetic field with a solar-cycle dependence
(IOP Publishing, 2008)
We present a refinement of the Fisk-Parker hybrid field of Burger and Hitge which now includes a region bordering the solar rotational equator where magnetic field footpoint motion occurs only through diffusive reconnection. ...
Possible evidence for a Fisk-type heliospheric magnetic field. 1. Analyzing Ulysses/Ket electron observations
(IOP Publishing, 2011)
The propagation of energetic charged particles in the heliospheric magnetic field is one of the fundamental problems in heliophysics. In particular, the structure of the heliospheric magnetic field remains an unsolved ...
Toward a greater understanding of the reduction of drift coefficients in the presence of turbulence
(IOP Publishing, 2017)
Drift effects play a significant role in the transport of charged particles in the heliosphere. A turbulent magnetic field is also known to reduce the effects of particle drifts. The exact nature of this reduction, however, ...
A simplified ab initio cosmic-ray modulation model with simulated time dependence and predictive capability
(IOP Publishing, 2018)
A simplified ab initio approach is followed to model cosmic-ray proton modulation, using a steady-state three-dimensional stochastic solver of the Parker transport equation that simulates some effects of time dependence. ...
