Stochastic acceleration and adiabatic heating of anomalous cosmic rays in the inner heliosheath

A brief discussion on the transport and acceleration of anomalous cosmic rays in the inner heliosheath is given with emphasis on stochastic acceleration and adiabatic heating of particles. Results from a numerical model is shown and compared to observations. We show that these acceleration processes play a major role in explaining Voyager 1 anomalous cosmic ray observations at the termination shock and in the inner heliosheath.
