Aims. We present synthetic bolometric and broad-band UBVRI light curves of SNe Ia for four selected 3D deflagration models of thermonuclear supernovae. Methods. The light curves are computed with the 1D hydro code stella, which models (multi-group time-dependent) nonequilibrium radiative transfer inside SN ejecta. Angle-averaged results from 3D hydrodynamical explosion simulations with the composition determined in a nucleosynthetic postprocessing step served as the input to the radiative… 
Theoretical light curves of type Ia supernovae
The first theoretical SN Ia light curves calculated with the time-dependent version of the general purpose model atmosphere code PHOENIX are presented, to produce light curves and spectra of hydro models of all types of supernovae.
3D deflagration simulations leaving bound remnants: a model for 2002cx-like Type Ia supernovae
cx-like supernovae are a sub-class of sub-luminous Type Ia supernovae. Their light curves and spectra are characterized by distinct features that indicate strong mixing of the explosion ejecta. Pure
OGLE14-073 – a promising pair-instability supernova candidate
The recently discovered bright type II supernova OGLE14-073 evolved very slowly. The light curve rose to maximum for 90 days from discovery and then declined at a rate compatible with the radioactive

Excavating the Explosion and Progenitor Properties of Type IIP Supernovae via Modeling of their Optical Light Curves.
Overall, it is difficult to characterize the explosion of Type IIP SNe by a single parameter, and that a range of parameters is needed.
An analytic bolometric light curve model of interaction-powered supernovae and its application to Type IIn supernovae
We present an analytic model for bolometric light curves which are powered by the interaction between supernova ejecta and a dense circumstellar medium. This model is aimed at modelling Type IIn
The Explosion and Progenitor Properties of Type IIP Supernovae Inferred from MESA and STELLA Modelling.
Hydrodynamical modeling is employed to investigate the explosion characteristics of eight Type IIP SNe and the properties of their progenitor stars, and creates evolutionary models using the MESA stellar evolution code, explodes these models, and simulates the optical light curves using the STELLA code.
