From mass-loss histories to lightcurves: a generalised framework for interaction-powered transients
Nikhil Sarin, Ryosuke Hirai
We introduce a fast (- ms) and generalised framework for modelling interaction-powered transients. The framework solves the thin-shell equations of motion for ejecta co…

Constraining the CSM structure and progenitor mass-loss history of interacting supernovae through 3D hydrodynamic modeling: The case of SN 2014C
S. Orlando, E. Greco, R. Hirai +9
We investigate SN 2014C using three-dimensional hydrodynamic modeling, focusing on its early interaction with dense circumstellar medium (CSM). Our objective is to uncover the pre-…
