Radiation Forcing
AstroBEAR now (2016) can calculate radiative transfer from single luminous object. Radiative transfer in AstroBEAR is first used in this research.
Mass Transfer and Disk Formation in AGB Binary Systems
We apply 2D ray tracing algorithm in radiative transfer calculation. Radiation will transfer momentum (exert radiation force on fluid). However, we do not consider radiation energy transfer. Therefore, we are solving the following equation.
We average the radiation flux over the azimutal angle (DustSublimationRadius=30. The radiation will be aborsbed by the gas and dust by opacity. In our paper, opacity can be a function of distance to the luminous object. You can checkout source/radforce.f90 Kappa_try(pos).
) and divide the polar angle ( ) into n small subdivision. The default is and you can change it in physics/physics_declarations.f90
