Numerical calculation of sub-luminous Type II-plateau supernova events

We are developing a specifically tailored radiation hydrodynamics Lagrangian code, that enables us to simulate the evolution of the main observables in supernova events. We aim at using this numerical tool to clarify the nature of the sub-luminous Type II-plateau supernovae progenitors by comparing the properties of iron core-collapse and electroncapture events. The code features and some preliminary results are briefly discussed.
