From mass-loss histories to lightcurves: a generalised framework for interaction-powered transients

Abstract We introduce a fast (~1–50 ms) and generalised public framework for modelling interaction-powered transients. The framework solves the thin-shell equations of motion for ejecta colliding with circumstellar material (CSM), and supports arbitrary CSM density and velocity profiles, including steady winds, eruptio...
