Description
Astrospheres are large scale magnetized plasma structures formed by the interaction between stellar winds and the surrounding interstellar medium (ISM). These systems play a fundamental role in regulating the transport and modulation of energetic charged particles. In this study, we will investigate the astrosphere of the runaway O-type star $\lambda$ Cephei using three dimensional magnetohydrodynamic (MHD) simulations with the heliosphere serving as a well observed benchmark for physical interpretation.
The work focuses on extracting and characterizing key plasma and magnetic field properties from high resolution simulations and transforming these into forms suitable for cosmic ray transport modeling. Building on heliospheric transport theory these MHD derived parameters are then used to calculate cosmic ray modulation inside these astrospheric cavities.
This study will also include an analysis between the stochastic cosmic ray modulation code and an independent finite difference transport model for comparison.
