SMACK 23: The versatile Rybicky-Hummer (RH) radiative transfer code

Abstract

I will give a brief introduction to the RH code, illustrated with some examples. The code is a general purpose radiative transfer code capable of solving the coupled equations of  radiative transfer and statistical equilibrium under general Non-LTE conditions in four different geometries, 1-, 2-, and 3D plane geometry, and spherical geometry. In addition the code can treat polarization under the Zeeman regime and partial frequency redistribution (PRD) in strong lines. In addition the code can be used to solve radiative transfer, optionally with polarization, in molecules. User tools with a graphical interface in IDL or Python routines to read the output , with example Jupyter notebooks are also available. If time permits I will run a few hands on examples.
