| Research Abstract |
We carry out 3-D numerical simulations of three very-high-energy gamma-ray binaries with different system and observational characteristics in order to have a unified view/understanding of the origin of various complicated activity in these gamma-ray binaries. Our simulations reveal 3-D time-dependent interaction features in unprecedented details. In systems with Be stars, the interaction structure strongly depends on the density of the Be disk.
