The SLAB-Diffusion package is a tool for modeling the radiative diffusion of photons through a slab of circumstellar material (CSM), e.g. in order to simulate the observables (effective blackbody temperature and radius) of an interacting Supernova.

>>> import SLAB_Diffusion
>>> SLAB_Diffusion.calculate_T_and_R_in_time()

The SLAB_Diffusion package was used in Soumagnac et al, 2018 to model the radiative diffusion of photons through a slab of circumstellar material.

The version available here assumes constant density (and hence constant diffusion constant D=h^2/t_D) in the slab. A more sophisticated version with varying density can be made available on demand by emailing maayane.soumagnac at weizmann.ac.il

If you are using SLAB-Diffusion, please reference Soumagnac et al. 2018
