#### 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 ...

#### 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 ...

#### A comparison of turbulence-reduced drift coefficients of importance for the modulation of galactic cosmic-ray protons in the supersonic solar wind

(Elsevier, 2015)

The study of the modulation of cosmic rays in the heliosphere relies heavily on a thorough understanding of the transport of these charged particles in the turbulent solar wind. Drift effects due to gradients and the ...

#### A cosmic-ray positron anisotropy due to two middle-aged, nearby pulsars?

(IOP Publishing, 2008)

Geminga and B0656+14 are the closest pulsars with characteristic ages in the range of 100 kyr to 1 Myr. They both have spin-down powers of the order 3 × 1034 ergs s–1 at present. The winds of these pulsars had most probably ...

#### Modeling the modulation of galactic and jovian electrons by stochastic processes

(IOP Publishing, 2011)

We present a newly developed numerical modulation model to study the transport of galactic and Jovian electrons in the heliosphere. The model employs stochastic differential equations (SDEs) to solve the corresponding ...

#### Time-dependent modulation of cosmic rays in the heliosphere

(Springer, 2014)

The time-dependent modulation of galactic cosmic rays in the heliosphere is studied
by computing intensities using a time-dependent modulation model. By introducing recent
theoretical advances in the transport coefficients ...

#### 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 ...

#### 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 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: an ab initio approach

(Springer Verlag, 2014)

A better understanding of cosmic-ray modulation
in the heliosphere can only be gained through a proper understanding
of the effects of turbulence on the diffusion and drift
of cosmic rays. We present an ab initio model ...
