In this work we present the analysis of a select group of hydrogen-richsupernovae (SNe), SN 2005cs, SN 2012aw y SN 2012ec, for which there isa good photometric and spectroscopic monitoring, as well aspre-explosion images with direct information from the putativeprogenitor star and post-explosion images confirming the disappearanceof the progenitor star. We determined physical parameters (mass,energy, radius) for this group of objects through their light curvesmodeling. We find the agreement between the masses derived from ourhydrodynamical modeling and those derived from the pre-explosioninformation available in the literature, better than achieved inprevious works.
