Query: Radiation hydrodynamics in simulations of the solar atmosphere   Nearly all energy generated by fusion in the solar core is ultimately
radiated away into space in the solar atmosphere, while the remaining energy is
carried away in the form of neutrinos. The exchange of energy between the solar
gas and the radiation field is thus an essential ingredient of atmospheric
modeling. The equations describing these interactions are known, but their
solution is so computationally expensive that they can only be solved in
approximate form in multi-dimensional radiation-MHD modeling. In this review, I
discuss the most commonly used approximations for energy exchange between gas
and radiation in the photosphere, chromosphere, and corona.
