We present spectroscopic and photometric data of a sample of Type II plateau Supernovae, covering a wide range of properties from the 56Ni rich, high luminosity events (e.g. SN 1992am) to the low-luminosity, 56Ni poor SNe (e.g. SN 1997D). We provide an observational framework to analyze correlations among observational data, physical parameters and progenitors characteristics of Type II supernovae.

Spectral analysis of type II supernovae
Abstract We present spectroscopic analysis of 63 type II supernovae. We present preliminary results on correlations between spectroscopic and photometric properties, focusing on light-curve decline
Photometric and spectroscopic properties of Type II-P supernovae
We study a sample of 23 Type II Plateau supernovae (SNe II-P), all observed with the same set of instruments. Analysis of their photometric evolution confirms that their typical plateau duration is
Hα Spectral Diversity of Type II Supernovae: Correlations with Photometric Properties
We present a spectroscopic analysis of the H{sub α} profiles of hydrogen-rich Type II supernovae. A total of 52 Type II supernovae having well-sampled optical light curves and spectral sequences were
SN 2005cs in M51 – I. The first month of evolution of a subluminous SN II plateau
Early-time optical observations of supernova (SN) 2005cs in the Whirlpool Galaxy (M51) are reported. Photometric data suggest that SN 2005cs is a moderately underluminous Type II plateau SN (SN IIP).
