#### A study of the global heliospheric modulation of galactic carbon

(Elsevier, 2014)

Observations of galactic Carbon in the heliosphere provide a useful tool with which a comprehensive description of the global
modulation of cosmic rays both inside and outside off the solar wind termination shock (TS) can ...

#### On the propagation times and energy losses of cosmic rays in the heliosphere

(American Geophysical Union, 2011)

We present calculations of the propagation times and energy losses of cosmic rays as they are transported through the heliosphere. By calculating these quantities for a spatially 1D scenario, we benchmark our numerical ...

#### 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 ...

#### 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 ...

#### Modulation of galactic protons in the heliosphere during the unusual solar minimum of 2006 to 2009

(Springer Verlag, 2014)

The last solar minimum activity period, and the consequent minimum modulation
conditions for cosmic rays, was unusual. The highest levels of galactic protons were
recorded at Earth in late 2009 in contrast to expectations. ...

#### Modelling and observing Jovian electron propagation times in the inner heliosphere

(ELSEVIER, 2013)

The propagation of Jovian electrons in interplanetary space was modelled by solving the relevant transport equation numerically through the use of stochastic differential equations. This approach allows us to calculate, ...

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

(Springer Verlag, 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 ...

#### Galactic cosmic rays in the outer heliosphere: theory and models

(Springer, 2011)

We review recent advances in the field of galactic cosmic ray transport in the distant heliosphere. The advent of globalMHD models brought about a better understanding of the three-dimensional structure of the interface ...

#### Modeling ground and space based cosmic ray observations

(Elsevier, 2012)

After entering our local astrosphere (called the heliosphere), galactic cosmic rays, as charged particles, are affected by the Sun’s turbulent magnetic field. This causes their intensities to decrease towards the inner ...

#### Cosmic-ray modulation equations

(Springer, 2011)

The temporal variation of the cosmic-ray intensity in the heliosphere is called cosmic-ray modulation. The main periodicity is the response to the 11-year solar activity cycle. Other variations include a 27-day solar ...
