The attribution of part of ‘global warming’ to changes in the total solar irradiance (TSI) is an important topic which is not, yet, fully understood. Here, we examine the TSI induced temperature (T) changes on a variety of time scales, from one day to centuries and beyond, using a variety of assumptions. Also considered is the latitude variation of the T-TSI correlations, where it appears...

The transport of charged particles in the heliosphere and the interstellar medium is governed by the interaction of particles and magnetic irregularities. For the transport of protons a rather simple model using a linear Alfven wave spectrum which follows the Kolmogorov distribution usualy yields good results. Even magnetostatic spectra may be used.
For the case of electron transport,...

We use numerical solutions of the focused transport equation to study the
evolution of the pitch-angle dependent distribution function of protons
in the vicinity of parallel and oblique shock waves and compare the results
with predictions of diffusive shock acceleration theory. We then consider the
case that a seed population of protons is injected close to the Sun
simultaneously with a...

The transport of charged particles in turbulent magnetic fields is a topic of
great interest in astrophysics, since our ability to successfully use cosmic
rays as astronomic messengers depends on our understanding of the transport
processes. One of the primary effects is the scattering of particles on
magnetic irregularities leading in the first instance to a change in the
pitch-angle...

Self–consistent Monte Carlo simulations have been a fruitful approach to model particle acceleration dynamically coupled with the foreshock development in quasi-parallel shocks. Our group has developed the global Coronal Shock Acceleration (CSA) Monte Carlo simulation capable of modeling self-consistent shock acceleration from the inner corona to the solar wind. However, in the currently used...

Heliospheric shocks are well-known accelerators of particles, responsible for
the creation of gradual solar energetic particle events. While the fact that
particle beams are formed in shock interactions is firmly established, many
open questions remain in regard to the microphysics of the acceleration process
and the shape of the resulting beam distribution.
The standard analytic...
